716399 - selecting text with empty tag doesn't select whole word

Status: NEW

(Core :: DOM: Selection, defect, P5)

Description

[Henrik Gemal]

The subject in my gmail doesn't let me select the entire word.

So I looked at HTML for it:

<h1>Produktion
<wbr></wbr>
sbekræftel</h1>

so when you double click on header I select only "sbekræftel" or "Produktion" and not the entire word

couldn't Firefox be made into selecting the entire text if the tag in the middel is empty?

Actual results:

Non-text frame always resets context in nsIFrame::PeekOffsetWord():

Then, next text node thinks that a new word starts/ends from its edge.

Therefore, empty element is treated as a word separator.
