Make resize triggers use default CSS writing mode

The Chromium community is moving to scroll position values indicated in
the CSSOM specification [1]. In order to launch the feature and analyze
potential broken URLs, they count pages setting the scroll position of
a scroller in non-default writing mode to a positive value. Websites
using javascript-detect-element-resize in RTL or vertical mode appear
in the top results and cause a lot of false positives [2]. In order to
avoid that, ensure that the resize triggers use the default writing
mode (direction: ltr and writing-mode: horizontal-tb).
