125810 - text shifts 1 pixel when selected with mouse (rounding error/twip-to-pixel)

Status: VERIFIED DUPLICATE of bug 87738

(Core :: Layout, defect)

Description

[Jeremy M. Dolan]

I thought there was an open bug on this, but I can only find the ones on images
(partially fixed), form elements, the scroll bar, and pretty much everything but
normal text.

I see this on a lot of pages, for a long time. It's 110% reproducable with the
top line of text here:

http://www.usdoj.gov/atr/cases/ms_tuncom/major/mtc-00027626.htm

Double clicking to select, or draging over 1 letter (or more), shifts the whole
top line, which on my browser size/dpi reads:

 "This document is available in two formats: this web page (for browsing
content) and PDF (comparable to original document formatting). To view the PDF
you will need Acrobat"

The whole line shifts 1 pixel right. Click reload, it jumps back 1 px left.
Touch it with the mouse, 1 pixel right, etc.

The second line isn't affected.
