1464596 - Misplaced iframe

Status: RESOLVED FIXED

(Core :: Layout: Floats, enhancement, P3)

Description

[Randell Jesup [:jesup] (needinfo me)]

I'm not sure why this iframe is misplaced, but it clearly is in beta and nightly at least.  It appears correctly in Chrome and Safari.  The misplaced iframe is the recaptcha; it appears far to the left and above where it should; it's inside a 304x78 div, and the iframe has size 304x78.  (from devtools the iframe's div appears properly centered, but too high.  the iframe itself is far to the right and lower)

Attachment: reduced test

Here's a reduced test.  It seems like the red box should be placed below the orange one, since it can't fit in its container (the grey box) but it could fit if it moves past the floats.

The purple box having a negative margin, so that it doesn't intrude into the grey container box seems necessary for the test case to misbehave.

(I'll look at this as time permits, to learn a bit about reflow.)

This was fixed in the Firefox 62 timeframe, possibly by bug 1466231.
