9894 - Text displays with glitches (boxes)

Status: RESOLVED WORKSFORME

(Core :: Layout, defect, P3)

Description

[Christine Hoffman]

This is an offshoot of bug #2742. That bug fix allowed content to be displayed
(using CSS display: block) within <STYLE> and <SCRIPT> elements. The content now
displays but with glitches on some platforms.

Using 7/13 M8 build, here are the results:

Win NT: Content displays correctly
Linux: Content displays correctly
Mac 8.5: Content displays correctly
Win 95: Content displays with glitches (small boxes)
Win 98: Content displays with glitches (small boxes)

Attached is a test case.

I'm not sure if this has any import, but is "text/text" (from the 7/14 testcase)
a valid mime type?
BTW the squares are the 'unrecognized character' glyph in Win32. The newline
characters are causing that. Saving the file with \r\n newlines causes the boxes
to occur in pairs.

Attachment: Updated test case with "text/plain" mime type

Even with the new testcase,the boxes still appeared on Win98. 8/2/99 M9 build.
Also, the CSS code appeared in the browser window.

This doesn't sound like a DOM bug; handing to chofmann for reassignment.

Bulk moving [testcase] code to new testcase keyword. Sorry for the spam!

This bug got lost.

Reassigning this to default layout owner.  It sounds like layout either needs to
learn how to handle '\r' characters in "\r\n" or it needs to prevent them from
being in the content model (which may well be incorrect for CDATA content).

I'll take this [ to see if the parser has anything to do with this ].

Comment 9

[harishd]

Yup, the layout got to handle this. Over to nisheeth.

This bug has been marked "future" because the original netscape engineer working 
on this is over-burdened. If you feel this is an error, that you or another
known resource will be working on this bug,or if it blocks your work in some way 
-- please attach your concern to the bug for reconsideration.

I'm seeing these glitches with Linux as well, using Mozilla 0.9.5 and also the 
latest nightly release.  Unfortunately, I'm not quite sure where they're coming 
from (I don't think the \r's have much to do with it, if at all).

Is this still a problem with recent builds?  We revamped the handling of \r at
some point....
