UserAgent: Mozilla/5.0 (Windows NT 6.3; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.36

Steps to reproduce the problem:
1. Click a CSS value containing a decimal in the styles panel of Chrome DevTools > Elements
2. Using the up arrow, "1.8em" becomes "2.8em"
3. Whoa, that text is large

What is the expected behavior?
This is a feature request. I believe a more expected behavior would be that the vertical arrow keys would alter the value in a more precision-aware manner.

For instance:
1.8em would increase/decrease at a step of .1, e.g. 1.7em, 1.8em, 1.9em, etc.
1.55em would increase/decrease at a step of .01, e.g. 1.54em, 1.55em, 1.56em
1em would increase/decrease at a step of 1, e.g. 0em, 1em, 2em

Most often I notice this while modifying font-size or alpha value of rgba, for both of which a step of 1 is not useful.

What went wrong?
Nothing, this is very, very minor...just thought I'd jot it here (as if you good folks don't have enough work to do :)

Did this work before? N/A
