One step necessary to check if something's a browser or AT issue is to
use a tool that shows you what the browser is actually exposing via the
accessibility API. On Windows for instance, you could use things like
Inspect
https://msdn.microsoft.com/en-us/library/windows/desktop/dd318521%28v=vs.85%29.aspx?f%5&MSPPError=-2147217396
or aViewer https://developer.paciellogroup.com/resources/aviewer/
(disclosure: I work for TPG)

This gives you an insight into whether or not a browser is exposing
stuff correctly or not. When just testing browser+AT combinations, one
of the problems is that you'll get AT also using heuristics and
error-correcting if browsers aren't exposing the correct stuff, so it
won't help you easily identify if a discrepancy of how one AT works with
a browser compared to another AT is a sign of the AT having issues, or
if it's the browser not exposing correct stuff and then ATs simply
having different heuristics to cope with that situation.
