Bug 202769 – Web Inspector: Modifying CSS selector by pressing Enter or Tab causes 2 CSS.setRuleSelector backend calls

• Component: Web Inspector
• Status: RESOLVED FIXED

[Nikita Vasilyev]

Editing a selector in the style editor causes at least two backend calls with the same data. There should be only one backend call.

Should we just skip calling `this._delegate.spreadsheetSelectorFieldDidCommit` altogether if !changed, instead of passing it as an argument?
