Bug 709014 patch 1: Honor margin-left and margin-right on elements in inline layout that have 0 width and/or height (commonly, inline-blocks). r=roc Prior to this patch, we failed to honor: * margin-left on elements in inline layout with 0 width and 0 height * margin-right on elements in inline layout with 0 width I think that was because the code in CanPlaceFrame to discard both margins when the width was 0 was running after the left-margin was applied, unless the later code in PlaceFrame (checking both width 0 and height 0) un-applied that left margin. The assertion count change in test_value_computation.html is due to 2 additional "bad width" assertions (I presume from honoring large margins that were previously ignored). The change to 538935-1-ref.html is to match an improvement in rendering of the margins in the test, where both sides of the margin are now honored. The change to layout/reftests/text-overflow/marker-basic-ref.html is to keep the reference (which uses margins) rendering the same way following the changes to margin handling. The new behavior (in the reftests added in layout/reftests/inline/) matches at least Chromium; I didn't check any other browsers. 2014-02-18 08:07:45 +04:00			`<!DOCTYPE HTML>`
