167751 - Wrapped link text not completely underlined and clickable

Status: RESOLVED WORKSFORME

(Core :: Web Painting, defect)

Description

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.2a) Gecko/20020910

In the news section of website of the the biggest Finnish newspaper 'Helsingin
Sanomat', I sometimes observe links that are not completely marked as links and
clickable.

That is, that parts of the text that is contained within A elements and that
normally is rendered as clickable links are not rendered as such. As far as I
can tell, this happens only when a link is warped on several lines. The part of
the link text that is not rendered as a link is the last part of the first line,
just before the line break.

I will attach screenshots that illustrate what I observe.

The URL specified is the page from where the screenshots are taken, but the
behaviour can be observed on other pages on the site, too.

This behaviour is not consistent, sometimes when I navigate back and forward
between pages the links are rendered normally again.

Reproducible: Sometimes

Steps to Reproduce:
1. Go to URL.

Actual Results:  
A part of the link text is not underlined and clickable.

Expected Results:  
All of the link text should be underlined and clickable.

Using maximized browser window, monitor resolution 1152 by 864.

Attachment: Reduced testcase

Since the original URL was on a site with dynamic content (daily news), the
issue cannot be observed there anymore.

I have now observed the behaviour also on
http://www.luottokunta.fi/visa_opas.html (first bulleted list), from where I
have developed the attached reduced testcase.

It is interesting that the behaviour occurs only when the misrendered word
within the A element contains a letter with an umlaut (in the testcase: ä).
When the letter with the umlaut is replaced with the corresponding non-umlauted
letter, all is OK. In the testcase I observe the bad rendering in the first and
second bullet, but not in the third.

Attachment: Second reduced testcase

The original reduced testcase works now for me with a fresh nightly build
(Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.3a) Gecko/20021127). But
the issue is still present in the sixth bullet of the first bulledted list on
the page http://www.luottokunta.fi/visa_opas.html, from where I have extracted
this new reduced testcase. In this testcase (and on the original page), the
text 'ja' at the end of the word 'Lisätietoja' is not treated as link text.

The font settings of the Mozilla profile have an effect, of course...

To reproduce:

1. Create a new Mozilla profile. (Not perhaps necessary.)
2. Change 'Preferences' -> 'Appearance' -> 'Fonts' -> 'Minimum font size' to 13.
3. View 'Second reduced testcase'.

I just upgraded to Linux at home, and have now observed the same behaviour on
this other platform also.

Using Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.2.1) Gecko/20030107, I
currently see partly non-underlined links on
<http://www.helsinginsanomat.fi/tuoreet/juttu.asp?id=20030110OL26> .

The Linux distribution is Gentoo, and I'm using Gnome on the desktop.

Yes, I'm still seeing the bug.

Well, actually I'm not seeing the exact same effect as previously but a similar
one. Attached is a screenshot that shows what I'm seeing currently.

Previously a part of the link was not underlined and clickable. Now the whole
link is underlined and clickable, but the underlined part is too long.

Whoops, forgot to define "currently". The screenshot was taken on a WinXP SP2
box with "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8a4)
Gecko/20040927". It's my work computer so I haven't updated my Mozilla in a
while. I'll have to check with a recent nightly.
