256174 - HR tag is rendered too large when SIZE specified as a decimal (less than 1.0)

Status: RESOLVED DUPLICATE of bug 52019

(Core :: Layout, defect)

Description

[DAK]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.1) Gecko/20040707

This has to do with the way Mozilla handles an improperly-written HR tag.
Technically, the page in question should be fixed, but the way Mozilla handles
the bug is a bug itself.  (This may be a "quirks mode" issue?)

According to the HTML spec, the size of an HR tag should be specified in pixels.
However, if an HR tag is improperly specified as a decimal less than one (as
though one could have a horizontal rule a half-pixel in size), Mozilla ignores
the decimal point.  Example: <hr size=.500>

Reproducible: Always
Steps to Reproduce:
1. Create a new HTML file
2. Type this code: <hr size=.500>
3. Save
4. View the results in the browser

Actual Results:  
The HR tag was rendered incorrectly.

Expected Results:  
Mozilla should treat fractional HR tags as though they had a height of zero (or
one).  This would, at least, make the page functional until the author of the
page could be convinced to fix the problem.

I discovered this bug at http://www.domainnamesystems.com, but it happens
everywhere.
