571426 - Uncached images' width not applied to parent width with float

Status: RESOLVED DUPLICATE of bug 546048

(Core :: DOM: CSS Object Model, defect)

Description

[pcrevival.zxq+bgzaccemail]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 6.0; en-GB; rv:1.9.2.3) Gecko/20100401 Firefox/3.6.3 ( .NET CLR 3.5.30729)
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 6.0; en-GB; rv:1.9.2.3) Gecko/20100401 Firefox/3.6.3 ( .NET CLR 3.5.30729)

When using float:left on a tag (tried div and span), any uncached images inside that don't have a width or height specified in the img tag will cause the parent to not include the width. (sorry if that's confusing).

When the page is refreshed the parent tag *will* float with the correct width.

Reproducible: Always

Steps to Reproduce:
1. Go to a site (eg. startrekguide.com) which contains an img tag within a div or span tag that is floated.
2. Refreshing the page will fix the problem.
Actual Results:  
The span tag appeared to be 'behind' the text on the page.

Expected Results:  
The span tag should float as normal with the image inside.

Can't seem to reproduce so far (on trunk), and code inspection on both 1.9.2 and trunk suggests that this should be working (we clear ancestor intrinsic widths)....

This doesn't show the problem either, over here... Does it for you?

Attachment: float bug

That's odd.
I will do more experimenting.

I've attached a screenshot of what it looks like on my computer.

Right; that's what I assumed you're seeing... but I just can't get that to happen so far.  :(

Here's another (simplified) testcase which works on my computer.

Is this something like bug 546048 ?
(I don't see any problems on my side with 1.9.2.6pre)

Comment 7

[Boris Zbarsky [:bzbarsky]]

Seems pretty likely, yes.  That would explain why my 1.9.2 builds aren't showing it, for sure.

Reporter, are you willing to test a current 1.9.2 nightly to see whether it has the problem?

Comment 8

[pcrevival.zxq+bgzaccemail]

Yes, I just tried in the latest nightly:
Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9.3a5pre) Gecko/20100610 Minefield/3.7a5pre ( .NET CLR 3.5.30729)

and the problem doesn't occur.

Thanks for helping!
