454525 - With caret browsing (F7) turned on, Page Up/Page Down scrolling gets stuck/trapped in HTML table

Status: NEW

(Thunderbird :: Message Reader UI, defect)

Description

[Joanmarie Diggs]

Attachment: test case

Steps to reproduce:

1. View the attached test case in Shredder
2. Tab to the first link
3. Press Page Down to get to the end of the message
4. Press Page Up to get to the top
5. Click on the last line of the message
6. Press Page Up to get to the top of the message
7. Press Page Down to get to the bottom.

Expected results: Page Down could be used to scroll to the very bottom of the message.  Similarly, Page Up could be used to scroll to the top.

Actual results. Page Down can be used to get most of the way through the message when starting from the top and Page Up can be used to get most of the way through the message when starting from the bottom.  However, both get stuck when the table boundary is reached.

Remove the table-related tags and the problem goes away.

Only happens when caret browsing (F7) is turned ON. Then happens reliably with testcase attachment 337808 [details]. Weird. And must be a bug in FF, not TB.
