Closes #17974

Description

Bind the open dropdown contents in Combo and Simple Combo to the control's disabled state using native inert. Options and other popup controls stop receiving pointer and keyboard input while disabled and become interactive again when re-enabled.

Motivation / Context

In Chrome, selecting Orange after the open control became disabled added Orange to the Combo selection and replaced Apple in Simple Combo. Both emitted a model change. With this patch, Apple remains selected and no change fires.
