REGRESSION(r128517): Percentage heights in quirks mode collapse when printing
​https://bugs.webkit.org/show_bug.cgi?id=108382

Reviewed by David Hyatt.

Source/WebCore:

r128517 clean up our containing block finding logic, but broke percentage
heights in quirks mode during printing since the RenderView would have 0 height.
Turns out we already had a long-standing bug where we'd incorrectly
treat collapse percentage heights on the body when printing as well.

Fix both bugs by changing the way we grab the logical height on the RenderView.
RenderView::computeLogicalHeight returns 0 when printing. For the purposes of
stretching and percentage heights, we instead need to return the pageLogicalHeight.

Tests: printing/quirks-percentage-height-body.html

printing/quirks-percentage-height.html
printing/standards-percentage-heights.html

  • rendering/RenderBox.cpp:

(WebCore::RenderBox::computeLogicalHeight):
This FIXME is outdated and already fixed. Also, call viewLogicalHeightForPercentages
which does the same logic except also correctly handles column RenderViews.

We're just clipping more content that you can't scroll to anyways. This looks
like an improvement to me.

We pass this test now!
