Automatic update from web-platform-tests Reland [css-text] New value 'break-spaces' for the white-space property This is a reland of a07642661ef7ff08c156e90394504a3a40afc9ea The build failure that caused the revert has been fixed in https://crrev.com/c/1430010 TBR=kojii@chromium.org Original change's description: > [css-text] New value 'break-spaces' for the white-space property > > Finally the CSS WG decided [1] to move back the 'break-spaces' value to > the 'white-space' property. This makes the parsing logic easier than > the previous approach of using the 'overflow-wrap' property. > > This new value prevents the white-space sequence to collapse and gives > breaking opportunities after every preserved white-space. > > https://drafts.csswg.org/css-text-3/#valdef-white-space-break-spaces > > Additionally, unlike 'pre-wrap', non-collapsible spaces or tabs at the > end of a line cannot be hung or visually collapsed, since we want them > to be preserved and broken. > > [1] https://github.com/w3c/csswg-drafts/pull/2841 > > Bug: 767634 > Change-Id: I55e888d4472de11c64c4b14e2710c6e3d1832e67 > Reviewed-on: https://chromium-review.googlesource.com/c/1136543 > Reviewed-by: Koji Ishii <kojii@chromium.org> > Commit-Queue: Javier Fernandez <jfernandez@igalia.com> > Cr-Commit-Position: refs/heads/master@{#623324} Bug: 767634 Change-Id: I987214a1b1275bfcc34cb2cadb2089344c4a7da4 Reviewed-on: https://chromium-review.googlesource.com/c/1415254 Reviewed-by: Javier Fernandez <jfernandez@igalia.com> Reviewed-by: Koji Ishii <kojii@chromium.org> Commit-Queue: Javier Fernandez <jfernandez@igalia.com> Cr-Commit-Position: refs/heads/master@{#625718} -- wpt-commits: 2e3722e50cb8fd2e3c70629c2ca2607e79c6d5e2 wpt-pr: 15042

<!--
|
|
white-space:break-spaces should cause the spaces at the end of the line to be preserved.
|
|
Since there is an allowed break point between the first space and the F,
|
|
that's where the line should wrap,
|
|
not between the L and the subsequent space.
