Description

18 years ago
When selecting text in the url above (which is a minimal example) mozilla dies
with an assertion:
###!!! ASSERTION: can't find generated content frame: 'lastChildFrame &&
IsGeneratedContentFrame(lastChildFrame)', file nsPresShell.cpp, line 3310
###!!! Break: at file nsPresShell.cpp, line 3310

To repeat, click in the middle of the text, hold down the mousebutton and drag
to the left and right a couple of times.

Here is the top of the backtrace:
