[UI Bug]: Dialog Component

[christoph2806]

Short Summary

There is an AlertDialog but it should be named "Dialog", and there are multiple CSS/JS bugs in it.

Steps to Reproduce

1. Create modal dialog
2. The backdrop is in the foreground, hiding the dialog
3. Dialog cannot be closed with "ESC"

Expected Behavior

1. The component should be named "Dialog" and not "AlertDialog". "Alert" is one instance, but there are others.
2. The backdrop should be behind the dialog
3. The dialog should close on "ESC" key.

Actual Behavior
