           Summary: Running execCommand with "Bold" twice does not remove
                    <b> elements if selection spans block elements with a
                    whitespace text node in between

            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: HTML Editing

Test case

Running document.execCommand("Bold", false, null) on the following selected HTML

<p>1</p>
<p>2</p>

... mutates that HTML into

<p><b>1</b></p>
<p><b>2</b></p>

Running the same command has no effect. However, running the same command on

<p>1</p><p>2</p>

... mutates that HTML into

<p><b>1</b></p><p><b>2</b></p>

... and running the command again returns the HTML to its original state. This suggest one possible cause is that the code mutating the HTML is ignoring the whitespace text node while the code for checking whether the selection is already bold is not ignoring the whitespace text node.
