The rule is just that new text on a tag boundary should not get tagged
by that tag. Basically left tag edges have right gravity, and right
tag edges have left gravity.

When I try this out, 1) doesn't work either - so I'm not sure what you
have done here or maybe I'm confused.

This may be a bug, if you have a small test case file it on bugzilla.gnome.org.

You could e.g. connect_after() to the insert_text signal and do fixups
on what tags are applied to the inserted text.
