Web Inspector: Empty attribute added to a DOM tree outline element should not add whitespace within the tag

• Component: Web Inspector
• Status: RESOLVED FIXED

[Brian Burg]

Steps to reproduce:

1. Click on a DOM element in the DOM tree with no attributes
2. <enter> to start editing
3. <enter> again to commit the edit

This adds an empty attribute to the UI, even though the attribute is never added in the backend.

If you instead add multiple spaces between steps 2 and 3, the edit is aborted and no extra space is added in the tag (presumably, this is because the backend rejected the change).

This is similar to https://bugs.webkit.org/show_bug.cgi?id=111036.

if (!newText.trim())

An empty string is already a falsy value.
