1949148 - Initial reflow of a block with orthogonal children may get incorrect intrinsic sizing

Status: NEW

(Core :: Layout, defect)

Description

[Jonathan Kew [:jfkthame]]

Attachment: testcase 1

See testcase. When initially loaded, it renders a red square, because the vertical-writing-mode <div> that should render as a green square (obscuring the red one) gets an inline-size (height) of zero because its orthogonal (horizontal) child did not report its correct height (block-size).

Zooming in/out of the testcase fixes the rendering. This is characteristic of examples where the problem is that the orthogonal child had not yet determined its block-size at the time when its parent was computing its intrinsic inline-size.
