Besides importing stuff from Chromium ...

This really seems like something a std::find would work for.  But it’s fine as-is.

The need for this comment indicates this should be an enumeration! But since this is imported code, land as-is and then post a patch to clean up the interface.

Can the vector be constructed directly with this data? Or at least sized properly, rather than having a separate allocation event, then a resize as we append.

This is true for all such cases.

Is this needed as part of this patch? Was it causing a build error for you?

You are right! Fixed.

Sure.

It looks like that the default cntr of Vector does nothing. Therefore we will have only one allocation event when we append.

Some kind of unified source build magic...
