Describe the bug
When the toggle for "No Footer" is enabled, and then disabled, the footer stays hidden. Tested this on Firefox and a clean Chromium browser.

To Reproduce
Steps to reproduce the behavior:

1. Go to 'https://quasarframework.github.io/quasar-ui-qiconpicker/demo'
2. Click on 'Playground -> No Footer'
3. The footer disappears as expected
4. Click on 'Playground -> No Footer' again
5. The footer does not reappear
6. There are no errors in the console.

Expected behavior
The footer should re-appear when the toggle is disabled.

Screenshots

Desktop (please complete the following information):

• OS: Kubuntu 22.04
• Browser Firefox 104.0.2 & Chromium 105.0.5195.125

Additional context
I don't know if there's an underlying issue with the quasar-ui-qiconpicker itself, or if it's just the demo website.
