No return after clicking "prevent this page from creating further dialogs"

[michi-zuri]

When testing Netlify with a potential customer (in a setting similar to a low-budget usability testing described by Steve Krug in his famous book Don't Make Me Think) I saw how the test person clicked the checkbox to prevent further dialogs. This caused her not to be able to finish a simple task: "create a new FAQ entry, then delete it".

Steps to reproduce the behavior:

1. Go to https://cms-demo.netlify.com/
2. Click login
3. Click on quick add-> FAQ
4. Write something, then click Save
5. Now click on Delete and cancel
6. click on Delete again and tick the checkbox to prevent further dialogs, then cancel.
7. Try to delete the page now, a normal person will not succeed within a few minutes.

Expected behavior
No possibility to silence confirmation dialogs.

Hey @michi-zuri I wasn't able to reproduce this with Chrome/Brave/Safari.
I was able to reproduce with Firefox and found this: https://superuser.com/questions/796842/disable-prevent-this-page-from-creating-additional-dialogs-for-certain-website

A possible solution is to switch to modals instead of alerts.
