This CL adds tests checking that

enable wasm.

The test landed with https://crrev.com/c/3179051 but it was removed
because of a conflict by https://crrev.com/c/3171519.

Test updates.

Mostly progressions, as expected, but there are two bits that deserve
some attention:

 * First there are two table tests that regress (because we were
   treating fit-content like auto). However Chromium fails the
   non-tentative one also, just in a different way, so I think it's
   worth punting on changing table layout and go to the CSSWG to figure
   out if "auto" is the desired behavior here.

 * Second, there's another test that regresses
   (position-absolute-replaced-minmax.html) for the same reason, we used
   to treat the size as "auto".

   The test that regresses comes from a Chromium crash
   (https://bugs.chromium.org/p/chromium/issues/detail?id=1010798) and
   the relevant behavior different also affects other intrinsic
   keywords, so I don't think we should address it here, and is unlikely
   to be a common case in the wild if we hadn't hit this before with
   other unprefixed keywords IMO.

   In any case I filed
   https://bugzilla.mozilla.org/show_bug.cgi?id=1732780 for this
   behavior difference to investigate later.

 * Third, I removed fit-content from min-{width,height}-invalid. They
   are valid sizing keywords in css-sizing-5, and they apply to these
   properties. Other browsers also parse it.

Make textarea::placeholder honor white-space.

This comes from https://hg.mozilla.org/mozilla-central/rev/0f28fd24bdf3,
and was done because of implementation limitations which don't apply
anymore (https://bugzilla.mozilla.org/show_bug.cgi?id=737786#c33):

 * white-space changes don't reframe anymore, they only reflow.
 * We fixed reframing of native-anonymous content to do the right thing.

This aligns <textarea> and <input>, so I think it should be
uncontroversial.

See w3c/csswg-drafts#6669 for the discussion
that prompted this.

part 18: Port editor/libeditor/crashtests/467647-1.html to WPT

I think that the crashtests marked as `needs-focus` should wait `focus` event
in the document.  I think that `focus` event is fired only when the window has
focus (*1) and `Element.focus()` steals focus unless chrome UI has focus (*2).
If the testing document hasn't get focus yet, `focus` event will be dispatched
later (*3).
