Comment 3 for bug 911276

Observed this to happen with the Adobe Reader 9.4 plugin too (nppdf.so). Only worse.

Steps to reproduce:
1) Open a pdf in a new tab
2) Adobe plugin renders pdf inside tab
3) open another tab
4) navigate to site (e.g. www.gmail.com)
5) interact with site (e.g. try to login)

Expected result:
interactions can be seen (e.g. clicking on links changes colour, entering into text boxes shows characters entered, etc)

Actual result:
can't see any interactions

This is worse since the pdf reader plugin is the whole size of the tab and not just limited to the size of a flash video so you really can't do anything :(
