See https://drafts.csswg.org/css-pseudo-4/#first-text-line 1. For a block container that establishes an inline formatting context, the "first formatted line" is its first line box, if it has one. Otherwise, there is no first formatted line. 2. Otherwise, for a block container that has block children, look inside the first in-flow block child (if any) and do #1 if it establishes an inline formatting context. Otherwise, do web-platform-tests#2. In short, we don't need to search for line boxes in blocks after the first block child. If there is no line in the first child, there's no "first formatted line". There's no spec for "last formatted line", but apply the same logic. I.e. if the last block child has no line, there's no "last formatted line". This allows us to simplify things a bit, especially when it comes to re-laying out (kTextBoxTrimEndDidNotApply). The only case where we need this now is for blocks inside inlines: If the last formatted line is inside a block-in-inline, we need to go back and re-lay it out if it turns out to be the last line (which isn't something we can check inside block-in-inline layout). Note: When adding support for block fragmentation, trimming at a fragmentainer's block end will be another case where we need to re-lay out. The motivation for this change was text box trimming inside block fragmentation (upcoming CL), and be able to add support for that and still be reasonably confident that it won't become too complicated. This fixes one existing test. Some other existing tests had to be updated because of this change (they were making incorrect assumptions about first/last formatted line). As a result of that, some new refs had to be added, since other tests were piggy-backing on the same ref.

This implements the core Sanitizer logic. This is still missing spec-mandated handling of "javascript:" URLs, and will have to be updated as the spec develops. But other than that, the basics are now there. ------------------ This a re-land of crrev.com/c/5922125. Patch set #1 is the original version, as reviewed and submitted there. Patch set web-platform-tests#2 contains the fix. Analysis of the bug is in https://issues.chromium.org/issues/356601280#comment16 Bug: 356601280, 379235386, 379246316 Change-Id: I06d4a9a378330cc76015e3922b9e288d9503881a Reviewed-on: https://chromium-review.googlesource.com/c/chromium/src/+/6021482 Reviewed-by: Yifan Luo <[email protected]> Reviewed-by: Joey Arhar <[email protected]> Commit-Queue: Daniel Vogelheim <[email protected]> Cr-Commit-Position: refs/heads/main@{#1385522}
