Hot Code replacement popup - "Don't show again"-button doesn't work

The button Don't show again button of the "hot code replacement warning" dialog doesn't work correctly. It always keeps reappearing. Furthermore multiple warnings are shown next to each other - which is a total overkill. At least the dialogs should be replaced, better even would be to hide them after some time (an assume the default action).

Environment

• Operating System: macOS 11.5.2 (20G95)
• JDK version: openjdk version "15" 2020-09-15
• Visual Studio Code version: 1.60.0-insider (also true for the regular version)
• Java extension version: v0.18.4
• Java Debugger extension version: v0.35.0

Steps To Reproduce

1. Change code in a running app, that causes the popup to appear
2. Click Don't show again
3. Change code in a running app, that causes the popup to appear

Current Result

Popup is shown again, despite the fact that I clicked Don't show again

Expected Result

Popup does never ever again appear.
