Status: ASSIGNED

Spinning off from bug 559728.

If type of focused <input> is changed, IME state should be updated, but it's not triggered yet even though caret visible issue was fixed.

Attachment: Bug 1817704 - Make `HTMLInputElement::HandleTypeChange()` notify `IMEStateManager` r=smaug!,#dom-core

Currently, nobody handles IME state at changing <input>.type.

The simplest fix is, make HandleTypeChange notify IMEStateManager of the
change and IMEStateManager update IME state and manage IMEContentObserver.
