We get into this block because `stencilBits` is 8 and the below `expect` succeeds because `stencil` is true in both the context and the options.  It looks like the stencil stuff passes and these changes are unneeded.

It looks like this and the widget tests are actually failing because of `premultipliedAlpha`, not because of `stencil`.  We request it as `false` and it comes back as `true` anyway.
