Subject: further fixes to font size combo: activate on defocus except when caused by esc;... 
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=4f81d4149fe01cf413e1134069961cd32738854c;p=inkscape.git

further fixes to font size combo: activate on defocus except when caused by esc; parse the value and serialize it back per css rules for setting style only if parsed successfully, to prevent corruption by bogus or empty values
