Issue number: resolves #30389
What is the current behavior?
Currently, when the element an ion-modal was presented from is removed, the modal stays presented and can be broken depending on the framework. This is unlike #30540, where children of open modals were being kept open. In this case, specifically the DOM element is being removed for whatever reason and the modal is staying open.
What is the new behavior?
We're now identifying our parent component on load and watching it with a mutation observer to determine if it gets removed from the DOM. If it does, we trigger a dismiss. This, conveniently, works nicely with #30540 and will dismiss all children and grandchildren as well.
Does this introduce a breaking change?
Other information
The issue this resolves was already marked closed, but on closer inspection I determined that was a mistake. I believed this issue was related to another one I was dealing with and it is, but it wasn't quite the same.
After this issue is merged, I believe we will have handled all avenues of possibly ending up with broken modals because of parent elements or modals being removed.
