AccName: reconsider appending space between inline text nodes #193

In review for WPT /accname/name/comp_text_node.html

<h2 class="ex" data-expectedlabel="heading label" data-testname="heading with text/comment/text nodes" id="labelTest1">
  heading<!-- with non-text node splitting concatenated text nodes -->label<!-- [sic] no extra spaces around first comment -->
</h2> 

WebKit results in PASS: expected "heading label" and got "heading label"
Chrome results in FAIL: expected "heading label" but got "headinglabel"

Discrepancy is that the AccName comp uses the term node, and these are two text nodes joined by a comment node and no additional whitespace.

Even if WebKit is to spec here, Chromium's implementation allows authors to choose whether they want the space, while WebKit always joins on a space, according to the spec. Worth revisiting?

Skipping this test in WPT for now.

• If this results in a spec change, please raise a new issue in AccName to update the WPT test, or
• If this results in no spec change, pleas assign back to me and I'll used this one to reinstate the test as written, confirming the WebKit behavior, not the Chromium behavior.
