In current Linux trunk, problem goes away when making viewport wider, but gets
massively worse when zooming text large enough to read.

Testcase #2

Testcase 2 is invalid markup because of the DTD given:
    Error Line 20, Column 19: there is no attribute "WIDTH"
    Error Line 20, Column 33: there is no attribute "BGCOLOR"
    Error Line 20, Column 49: there is no attribute "NOWRAP"

The strict DTDs for html consider all presentation attributes except CSS markup to be invalid.

Thought this could have been a duplicate of bug 277232 and may possibly still be related, but forcing quirks mode and/or changing to a DTD in which the nowrap attribute is considered valid doesn't change the testcase result. Could also be related to 318262 but also not exact duplicate.
