[orca-list] Chromium performance degraded after orca update

[Kyle <kyle4jesus gmail com>]

I'm currently using the chromium browser for work. The job requires that 
I be able to click numbers at the bottom of the page that are clickable 
items, but also that I read blocks of text one after another after 
activating a button. The blocks of text are survey questions, and the 
buttons are for the answers. So as soon as I answer one question, I need 
to be prepared to read the next question. I had this working really well 
using Orca 3.36.5 and 3.36.6, but I just got 3.38 yesterday and 
immediately noticed a huge performance hit. The clickable numbers at the 
bottom of the page now take about 1.5 to 2 seconds to speak, and by that 
time they are usually gone. The questions that I have to read are now 
taking me almost 3 seconds to be spoken, which causes an awkward pause. 
I also noticed that 3.38 is focusing the desktop or the MATE menu bar 
sometimes when I try to click a number, throwing me completely out of 
the browser window and making me switch back to it. This also wasn't 
happening in 3.36.6. I was just getting some clicks reported as not 
found, but I could still move. I tried switching over to git master, but 
I am seeing the same problems with performance, although I don't recall 
getting thrown off the browser window. I have successfully downgraded 
back to Orca 3.36.6 and no longer have the performance issues. The 
clickable numbers are spoken quickly enough to click most of them, and 
my questions are speaking much more quickly. Thanks for any help with 
this issue.
