43732 - Layout of page changes with each character entered

Status: VERIFIED FIXED

(Core :: Layout, defect, P3)

Description

[Stephen P. Morse]

Go to URL indicated.  Note that the page dances around a few times before it 
finishes loading.  Type characters into any field slowly.  Note that the entire 
page shifts with each character typed.  On first character, form shifts slightly 
to the right.  On second character form shifts twice as far to the left but 
image shifts over considerably to the right.  On third character we get back to 
the original display.  Pattern keeps repeating with every group of three 
characters entered.

This might be related to bug 42451.

Nominating for nsbeta2.

Putting on [NEED INFO] radar. Are there any top100 sites that show this type of 
behavior (please try filling out forms on those sites and let us know).

Comment 3

[Stephen P. Morse]

I have no idea if there are any top-100 sites that exhibit this behavior.

Comment 4

[Daniel Veditz [:dveditz]]

Doesn't the fact that this behavior happens at all, and is a regression, worry 
anyone? Just because it's not visible on other sites doesn't mean we're not 
churning under the surface on all the other sites.

Putting on [nsbeta2+] radar for beta2 fix.

This was part of Clayton's list that got marked beta2+ by the PDT today, so I 
asked for it to get re-assigned to me for initial triage.  On closer examination 
this seems like an incremental reflow bug, so I am re-assigning it to you.

dveditz:  This sounds like an existing incremental reflow bug that was exposed
by ender-lite.  With ender-lite, the text field contents are part of the same
document, so incremental reflows can have affects on other parts of the
document.  The performance issues are bug 42471.

Fixed.
