Dropdowns do not correctly sync with editor state.

1. Type '123abc'
2. Highlight 'abc' and set it's size to 'huge'.
3. Move your cursor over 123.

The dropdown's value should switch to 'Normal' but it remains 'Huge'. The editor's delta is correct though.

This is more than just a cosmetic issue, because if you were to highlight '123' with the intention of making it 'Huge', you wouldn't be able to (it's technically already selected and selecting it does nothing). To force the matter, you currently have to first set the size to something other than 'Huge' or 'Normal', and then switch back to what you actually want.
