Bug 48479 – queryCommandValue should fall back to queryCommandState

• Component: HTML Editing
• Status: RESOLVED FIXED

[Ryosuke Niwa]

queryCommandValue should return 'true' or 'false' when the command doesn't return any string and queryCommandState is supported.  This is consistent with IE and will greatly improve WebKit's score on http://www.browserscope.org/richtext2/test

I’m surprised that this functions works that way, but change looks OK. Do any of the test cases cover the mapping of mixed state to "false"?

The function name here isn't all that clear.

I'm pretty certain that query-command-state.js do test that.

I don't like that name either but couldn't come up with a better name.  isEquivalentBooleanValue?  isBooleanValueEqualTo?  isBooleanEqualTo?

Tony pointed out that we can just do centerValue != center.toString() and get rid of the function.  I'll land after making this change.
