Web Inspector: Styles: PropertiesChanged shouldn't fire when old and new text are both empty

• Component: Web Inspector
• Status: RESOLVED FIXED

[Nikita Vasilyev]

inspector/css/modify-css-property-race.html is still failing on debug build (and debug build only!) because of this.

Also, it adds an unnecessary entropy to the universe :)

oops :P

Rather than compare the hardcoded 10 and 11, you could save a `previousHeightNumber` and ensure that the first one is greater than 10 and the second one is greater than `previousHeightNumber` (and change the text to say "Height should have increased from 10px" so you don't have to log the actual increased value).

Ditto (72).

I actually find it easier to follow when it's hardcoded there. However, I do like the less "robotic" assert messages!

After the fixes in https://trac.webkit.org/changeset/241011/webkit

inspector/css/modify-css-property-race.html
