Test history suggests that this regressed with https://trac.webkit.org/changeset/263098/webkit

[Ryan Haddad]

Youenn says he will look at this tomorrow.

Marked tests as failing to keep EWS moving quickly in the interim.

Test seem to pass in windows by reverting a change that was not mandatory for https://trac.webkit.org/changeset/263098/webkit.
I am not quite sure why and we should probably get back to it at some point.

If this fixes it, I don't oppose.  Definitely strange.

If this value is sent cross process with Encoder/Decoder, changing from bool to uint8_t might require specializing EnumTraits. So it might be slightly trickier than just reverting. I see no test failures, I guess this is not done with this enumeration?

This fixes it according the bots.

Issue is WK1 and I do not think this is encoder/decoder.
Maybe this is Windows compiler specific.
