582384 - When hovering over some corners of elem with transform & non-transform transitions, the non-transform completes but transform does not

Status: RESOLVED DUPLICATE of bug 582379

(Core :: CSS Parsing and Computation, defect)

Description

[Daniel Holbert [:dholbert]]

Attachment: testcase 1

STEPS TO REPRODUCE:
 1. Load URL or testcase.
 2. Move cursor to absolute lower-right corner of the div (point 'b' in testcase)

EXPECTED RESULTS:
Transform & color transitions should "jitter" back and forth between intermediate states, as the div enters & leaves 'hover' status.

ACTUAL RESULTS:
The transform transition jitters, as expected, but the color transitions complete, arriving at the final values (white text on red background).  There's usually a little bit of "jitter" with the color values, but they tend to get past that pretty quickly and stabilize on the final value.

I'm testing with today's linux x86_64 nightly, btw:

Attachment: testcase 2: with font-size, too

This testcase also has a 'font-size' transition, which matches the behavior of 'color', completing its transition.

NOTE: I can get closer to (or even reach?) the EXPECTED RESULTS if I position my cursor a little ways to the left of the 'b' character, in both testcases attached so far.  However, if I position my cursor *on* the 'b' character (its resting position), I always get ACTUAL RESULTS.
