This reverts commit 7a13d8a0.

This change broke some internal tests that set the text editing value to
the same thing (the empty string) twice in a row. Note that in that
case, the developer had subclassed EditableTextState and overridden the
updateEditingValue method, which may or may not be relevant to the
failure.

This reverts commit 83d4d63a.

* Reland "Fix custom Elements that wants to decorate State.build (#49925)" (#50068)"

This reverts commit 62fdcb03.

Updates stack filtering for new frames in stateful element
