white-space: pre; in table.diff td {} seems works for display only, it seems to be "pre-line" when copying.

[Boris Zbarsky [:bzbarsky]]

This works correctly if I highlight at least two lines.  So seems like an issue only with selections that don't include the actual node the style is on or something like that.

Simple testcase:

  data:text/html,<div style="white-space: pre">Some     text</div>

and highlighting from 'm' to 'x'.  Note that if I replace the "div" with a "span" the problem disappears.

This has nothing to do with CSS parsing; this is all text serializer stuff.  Ehsan, do we even have a place where this should live, other than "DOM"?

Bulk-downgrade of unassigned, 4 years untouched DOM/Storage bugs' priority.

If you have reason to believe this is wrong (especially for the severity), please write a comment and ni :jstutte.
