Steps to reproduce:
1. Launch Mozilla.
2. Navigate to the following attachment.

Actual result:
Fourth line of the text overlap with the right floater.

Expected result:
text should not overlap with floats.

Observed on:
2000060220 nightly build on Windows 2000.

Reassiging to Kevin for bug triage.

Steve, could you look at this? Unless clip is set on views for the floaters they
will display their contents.

(This bug will probably reappear once Steve checks in his float percentage width 
fix today (the testcase depends on that bug being fixed.)

This looks bad.  Nominating nsbeta3 because it's a standards-compliance issue, 
and it probably will affect some real web pages (especially as more pages start 
using CSS floats for layout).

As per meeting with ChrisD today, taking QA.

Comment 7 User image Hixie (not reading bugmail) 2000-08-04 22:54:31 PDT
David: The first testcase demonstrates a bug in the quirks mode "don't push
floats down" code that causes overlaps, so you are probably correct; we should
disable that quirk as much as possible.

The new testcase gets around this problem and demonstrates the issue very well.
Note that this bug shows up on a WaSP test page. (However, this is probably one
of our less dramatic float errors...)

Denied beta3: too many float bugs to fix them all for beta3
Comment 9 User image Hixie (not reading bugmail) 2000-08-25 13:41:59 PDT
This will make lots of pages look bad, and it makes it unsafe to use floats
around text, which is the main use of floats.

I know we still do not have enough resources to get this fixed. However:

Removing [nsbeta3-] to put this floater bug (and 3 others) back onto the 
developer radar, as per suggestion by Gerardo.
Comment 11 User image buster 2000-09-19 10:28:34 PDT
changed (beta3 minus per triaging) to [nsbeta3-] so searches work correctly

I'm pretty sure this has the same cause as bug 25888 -- see my 2001-09-17 13:56
comment on bug 86947.

Build reassigning Buster's bugs to Marc.
Comment 16 User image Marc Attinasi 2002-02-28 15:58:56 PST
It would be nice to fix this, but for Mozilla 1.0 we are already way overloaded
just with crashers and dataloss bugs.

Confirmed using FizzillaCFM/2002070913. Setting Platform=All.

Marking dependency on bug 25888, but not duplicate, since this is a more
complicated variant of the problem that might not be fixed by any fix to bug
25888 (although it should be fixed by the *right* fix).
