Drawer component inherit from ValueElement

[xaptronic]

Currently, LeftDrawer/RightDrawer/Drawer implements show/hide/toggle to control whether the drawer is open via it's model-value prop - however it doesn't use ValueElement functionality, so one cannot use property binding to control it's state.

Is there a reason this is so, or would a PR to change the base class of Drawer be a welcome addition?

Hi @xaptronic,

That's a good question! I can't remember a specific reason why drawers don't inherit from ValueElement like ui.header and ui.footer. We should definitely try to fix that. A PR would be very welcome! 🙂
