Webkit treats form fields just like every other element and when both left and right are set, it stretches them horizontally to satisfy both declarations.

However this, convenient as it may be, is opposed to both what every other engine is doing AND the specification:
"The used value of ‘width’ and ‘height’ is determined as for inline replaced elements."

A blog post describing this issue: http://snook.ca/archives/html_and_css/absolute-position-textarea 
It also happens with inputs: http://jsfiddle.net/leaverou/PTxSE/4/show
But not all replaced elements: http://jsfiddle.net/leaverou/PTxSE/3/show
It also doesn't happen with top/bottom, only left/right: http://jsfiddle.net/leaverou/PTxSE/5/show

I also tested on Windows, and it's reproducible there as well.
