65856 - Selection in composer is erratic

Status: VERIFIED DUPLICATE of bug 47469

When I double-click on text in the composer, the text highlighted and selected
is not consistent

Reproducible: Sometimes
Steps to Reproduce:
1. Open composer, type some English text.
2. Double-click on various words.

Actual Results:  Normally, double-clicking a word selects that word. Somtimes it
selects part of the word. Sometimes, it selects two adjacent words. Sometimes,
it selects the word plus the adjacent punctuation, plus a following space.
Sometimes it selects nothing at all.

Expected Results:  Double-clicking a word selects the whole word but not
adjancent punctuation or white space.

When I tested this, I made sure that all the test words were pure words: not
hyphenated or with non-alphabetic characters. I made sure that I always clicked
near the centre of the word (I have the font size turned up large to help with
this).

Sometime, when only part of the target word was selected, the selection went
from the first character to the last character rightward of the I-beam cursor.

It seems to misbehave randomly, failing on maybe 10% of double clicks. It
doesn't fail consistently on particular words; it usually gets it right if I
repeat the double click. The type of text doesn't seem to matter; it happens in
both paragraphs and headings.

Over to editor. Is this a known issue? Should this go to selection component?
