BugFix - 40488 - Unable To Add Spied Element To POM#3818
Conversation
…d crashes. RC: We were calling AddRange method on Properties and Locator properties of HTMLElementInfo from a background thread. This method call triggers CollectionChanged event, which then modified some UI elements. We cannot modify UI elements from background thread. Fix: Call AddRange method from outside the background thread and from the calling thread.
