1329492 - editting filters with long list of conditions, tab doesn't navigate through all conditions. Ends at last visible condition.

Status: NEW

(Thunderbird :: Filters, defect)

Description

[Wayne Mery (:wsmwk)]

+++ This bug was initially created as a clone of Bug #411507 +++

I wonder if this is impacted by code similar to Bug 1312172.

Steps
1. have a filter that has more conditions than fit in the display when edit is chosen
2. tab through the conditions

Actual results: after the last VISIBLE condition, tab skips to actions section, and does not go through "not visible" conditions

expected results: tab moves through all conditions before skipping to actions section

I'd rather think this would be a shortcoming or design of the listbox XUL widget. I think it even does some internal optimizations so that the non-visible rows aren't fully initialized before being scrolled into view. So I'm not sure if you can even tab into such rows.

Yes it may be something like bug 1312172, but much harder. The XUL implementation must upon clicking tab check if there is something more to scroll to, do it, then focus the next element. If there is nothing to scroll to, focus the next element outside the list (actions). I don't know how much of that is natively done in XUL already.
