Oh, it is about double.... then the real fix would be to change our WebIDL interpreter. It seems fine to change it in Context2D in the meantime.

> then the real fix would be to change our WebIDL interpreter. Is there a bug tracking the right fix? It would be helpful to have a FIXME in code referencing the bug, so that we can more easily remove this workaround when it's no longer needed.

It would be helpful to have a FIXME in code referencing the bug, so that we can more easily remove this workaround when it's no longer needed. yes, see https://bugs.webkit.org/show_bug.cgi?id=101783 The 'isFinite' testing is all over the codebase. Do you want me to add a todo to just the lines that I touched?

If it's already all over the place, then there is no point indeed.
