1204899 - It's really hard to see inspector tooltip twitching when element is constantly changing width

Status: RESOLVED DUPLICATE of bug 1143675

(DevTools :: Inspector, defect)

Description

[arni2033]

STR:   (Win7_64, Nightly 43, 32bit, ID 20150913030204, new profile, safe mode)
1. Open http://jsfiddle.net/laukstein/LLNsV/5/ (testcase from bug 851875)
2. Open Inspector, type "div.motion-width > ul.list-a > li:first-child" without quotes in "Search with CSS selector" field
3. Hover mouse over selected element [tooltip will appear near that element]

Result:       You can see how tooltip is twitching when element's width crosses integers (because integer numbers are 1-3 symbols in length ("187"), and frational numbers are 1-6 symbols in length ("103.408"). So this bug is reproducible even if the change of element's width is barely visible.

Expectations: Tooltip should be easier to read

Leaving it Unconfirmed because this issue really looks like request. Maybe it could be fixed by moving element's dimentions to another line in tooltip and setting some fixed width for them.
