Re: [orca-list] The problem with navigation by heading randomly placing me at the end or beginning of the page is back

Not sure if related but similar, go here: again docs.microsoft.com, I
experience all these bugs mostly there...
https://docs.microsoft.com/en-us/aspnet/core/migration/31-to-50?view=aspnetcore-3.1&tabs=visual-studio
Now, try to navigate between headings to "Model binding changes in ASP
.net core mvc and razor pages" or similar
Then, start pressing down arrow. After two presses of down arrow, when
you get past the heading, you suddenly land on the feedback heading.
It didn't stop after I restarted orca so it seems always reproducible,
and as said my chrome version is currently 88.0.4292.2

uhm not sure how much, but I'd guess this one is less than half of a
second, may as well be around 200-300ms so it would be what you
describe, probably. The lag also happens when going to some heading and
pressing down arrow, but I'd guess it's of similar length.

How big of a lag? I just cycled through all the headings at level 2,
wrapping to top, several times. The laggiest response time was 0.2678
seconds. Everything else was much faster. And the reason it took a
quarter of a second when it did lag is that the page added a heading
(or claimed to add a heading). As a result, Orca had to clear its
structural navigation cache.

If you're seeing a much more significant lag than that, then please
send a full debug.out.

Thanks again!

Well, installed it and currently it seems to work, but it's also a
bit
laggy. For example if I press down arrow on some headings I actually
feel the lag. Also try to navigate through headings here
https://docs.microsoft.com/en-us/dotnet/core/compatibility/3.1-5.0
... I
experience lags from time to time, for example if I go to the top of
this page and start pressing 2, then every 3 or 4 presses there is a
lag.

Should be enough, yes. Please let me know what you find. Thanks

The newest unstable I can find that I can now install is exactly
88.0.4292.2 - is that enough?

Not sure. Maybe it's a timing issue, maybe it's a coincidence.
Lots
of
accessibility-related fixes and other changes have been
landing.

The parent-changed fix (along with other things) should appear
in 88.0.4286.0.

Could you tell me how is that possible this bug was still
happening
in
many instances, just more randomly, when orca did have this
workaround
that didn't use the cache? I mean is that something that
could be
happening?
Also when could I expect that to land in the actual google-
chrome-
unstable?

I was able to reproduce this in google-chrome-unstable, but
have
not
yet been able to do so in my local build of Chromium. I
recently
landed
a change in Chromium to emit parent-changed events which
fixes
a
bug
similar to what you describe. So, could you please see if
you
can
reproduce this problem in a Chromium snapshot?

Thanks!

Hi,
You remember when I told you about the issue you couldn't
reproduce
about navigation by headings?
It actually never stopped happening, but I couldn't
reproduce
it
consistently. Currently I managed to do it, it seems,
except
that
I
am
not fully sure it's exactly the same issue. I will send
debug.out
in
the
next mail.
So generally using orca master, google chrome unstable
version
87.0.4263.3 and went to this page:
https://docs.microsoft.com/en-us/aspnet/core/fundamentals/routing?view=aspnetcore-5.0
You can now try to navigate by heading. for some reason
if I
do
this
fast enough it works, but if I do it slower, then after
some
time
I
will
likely land on the first heading suddenly.
Also, what is not shown in the debug.out because I
forgot, is
that
pressing down arrow from the heading suddenly drops me
off to
the
bottom
of the page. I will try to reproduce that too and send
you
another
one then.
