Status: RESOLVED DUPLICATE of bug 358452

(Firefox :: General, defect)

Description

[kf]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.2.17) Gecko/20110429 CentOS/3.6-1.el5.centos Firefox/3.6.17
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.2.17) Gecko/20110429 CentOS/3.6-1.el5.centos Firefox/3.6.17

Past the code below into an HTML page and try it:

<p><dfn title="Where the text assigned to the title arg
contains a newline, HTML renderer should insert a space
character. Otherwise
the
words
are
run
together.">Put cursor over this text to see pop-up text (value of
title arg)</dfn></p>

This happens with any html tag which accepts a title arg.

Reproducible: Always

Steps to Reproduce:
1.Copy and paste the text in Details above into an HTML page.
2.Refresh that page.
3.Hold the cursor over the newly-inserted text.
4.Observe that where the code has a newline separating words, the words before and after the newline are run together asiftheyareoneword.

Actual Results:  
As said above, the words before and after the newline are run together asiftheyareoneword.  

Expected Results:  
In parsing the text assigned to the 'title' arg, a newline should be replaced by a space... this to ensure a space is inserted between words and so that words aren't runtogetherlikethey'reoneword.

Thanks for fixing this and all the other nice work you do.

Spaces are the only allowed control characters according to: http://www.whatwg.org/specs/web-apps/current-work/multipage/syntax.html#syntax-text

HTML5 requires a line break in title tooltips
