-----------
Padding end should contribute to scrollable overflow when inline direction is
flipped
https://bugs.webkit.org/show_bug.cgi?id=297466
Reviewed by Antti Koivisto.
When content is inline-flipped, the padding end (in case of simple horizontal
flow, it is visually right padding),
contributes to scrollable overflow where it may produce a scrollable rect that
starts outside of the container.
e.g.
<div style="direction: rtl; width: 1200px; padding-left: 1000px">
<div style="width: 400px">
1200px
-200px _______________________
______|___________ ________ |
| | || ||
| 1000px || 400px ||
|______|___________||________||
|______________________|
The 400px wide child box (aligned at the right edge of the container) is
positioned at 800px. Now the padding (end) needs 1000px space which "pushes"
the scrollable overflow all the way to -200px.
