Status: NEW

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.1) Gecko/20090616 Firefox/3.5

When you select text before a <video> and then continue moving the mouse to include selecting the <video> itself and the text after it, the selection stops highlighting.  The text before the <video> remains selected even when you then select other text.

Reproducible: Always

Steps to Reproduce:
1.Select text before a <video>
2.Continue to hold the mouse button and select the <video> and the text after it

Actual Results:  
The text after the <video> is not selected.  The text selection before the <video> is "stuck".

Expected Results:  
Text selection after the video should continue until the mouse button is released.  (I wouldn't necessarily expect the <video> to get selected also, but I suppose that would match what happens with images).

I also found this bug, while trying to crash Firefox with the Isobox (I didn't succeed).

But look at the attachment.

I have no clue what the bug is that your trying to show there but please file a separate bug for that.  Bug reports are for one specific bug only.

With <audio> Element this happens, too (see duped Bug Report).
Wondering if this is the right Component though.

Text selection is a layout concern. Is this still an issue anyway?

The severity field for this bug is relatively low, S3. However, the bug has 3 duplicates.
:dholbert, could you consider increasing the bug severity?

This seems to work as intended here, attached is what I see on e.g. https://blog.paul.cx/post/profiling-firefox-media-workloads/, that has an inline video.

The last needinfo from me was triggered in error by recent activity on the bug. I'm clearing the needinfo since this is a very old bug and I don't know if it's still relevant.
