Assertion hit under IdTargetObserverRegistry::notifyObservers()
https://bugs.webkit.org/show_bug.cgi?id=247592
rdar://101454107
Reviewed by Aditya Keerthi, Wenson Hsieh and Geoffrey Garen.
ListAttributeTargetObserver::idTargetChanged() is not safe to re-enter. As
a result,
we have an assertion and a runtime check to protect against this. However,
it was
still possible to hit this assertion in debug.
ListAttributeTargetObserver::idTargetChanged() would call
TextFieldInputType::dataListMayHaveChanged() which could run script by
calling
createDataListDropdownIndicator(). The script could then change the datalist
element's id, which would attempt to re-enter.
This patch addresses the issue by calling dataListMayHaveChanged()
asynchronously.
