The x-axis legend text in the following site is incorrectly positioned: http://www.highcharts.com/demo/spline-irregular-time (Originally reported: crbug.com/112713) I've tracked this down to a regression between r105048 and r105082 and I suspect it was caused by https://bugs.webkit.org/show_bug.cgi?id=65711.
Marking as a duplicate of https://bugs.webkit.org/show_bug.cgi?id=78385 as the patch fixes this bug as well. *** This bug has been marked as a duplicate of bug 78385 ***
