## What is the current behavior?
<!-- Please describe the current behavior that you are modifying. -->

In
30e3a1485d
I removed the `deepWait` call from popover/modal in custom element
bundle environments (React and Vue as of writing). This had an
unintended side effect where WebKit/iOS would not play the modal enter
animation correctly because the inner contents are mounted
mid-animation. This does not impact other mobile platforms.

This only impacted the modal because popover had a patch in
be9a399eee
which causes it to wait for the JS Framework to finish mounting before
proceeding with the transition.

## What is the new behavior?
<!-- Please describe the behavior or changes that are being added by
this PR. -->

- Modal now emits `ionMount` event and waits 2 frames before proceeding
with the animation.

Note 1: The JS Framework overlay components were already updated to
support this `ionMount` event in
be9a399eee.

I also updated the modal Angular component to listen for `ionMount`. It
is not needed right now because Angular does not use the custom elements
bundle and therefore does not call `ionMount` (it runs the `deepReady`
function though). However, if we move Angular to support the custom
elements bundle in the future this may become an issue. This behavior
currently exists in the popover component for Angular too.

Note 2: This does appear to be a WebKit bug since it does not happen on
Android. However, this patch seems fairly safe which is why I've opted
to try and fix it internally instead of waiting for a patch from Apple.
