47252 - reflow wipes out TFOOT when mouse over button and TBODY style=overflow:auto

Status: VERIFIED FIXED

(Core :: Layout: Tables, defect, P4)

Description

[KenW]

From Bugzilla Helper:
User-Agent: Mozilla/4.72 [en] (Win95; U)
BuildID:    2000072808

I have a table with the TBODY set to a fixed height and overflow:auto. In the 
table's TFOOT, I have a form with a submit button. When I pass the mouse over 
the submit button, the table is redrawn and the submit button is wiped out. 
Reloading the page fixes the display until I pass the mouse over the submit 
button again.

There seem to be many bugs with table rendering and reflows so this may be 
equivalent to one of the other ones, although I couldn't find one that seemed to 
match the above test case.

Reproducible: Always
Steps to Reproduce:
1. Load the test case (will make an attachment) in mozilla
2. Pass the mouse over the submit button

Actual Results:  Table is redrawn, wiping out submit button.			
				

Expected Results:  Table is not redrawn, submit button highlights (or not).

Attachment: test case referred to in bug submission

the testcase is a real mess on my build (win95, 080108).  The table covers the
button, and the button is unclickable.

In order to see the reflow problem it may be necessayry to reload the testcase.
Confirming the bug

important reflow/layout bug.  makes the page completely unusable.  nominated for
nsbeta3

Comment 6

[Marc Attinasi]

Approving for beta3: This could be related to the problem of table style 
contexts being parented incorrectly, causing reframes when you hover over links 
or buttons in a table (bug 45210).

Marking depends on 30418: it is at least related.

Tested on Win 95 with 8/31 build, the problem stated in the Summary is no longer 
happening although there is a problem. When I pass the mouse over the submit 
button, nothing happens; the submit button is NOT wiped out. However, text in 
the TBODY is overlapping the submit button.

[Phil Peterson]

PDT thinks this is a P4 with current bug description

Fixed. This was closely related to the fix for 30418.
