Cached blocks are not invalidated when settings change

I have created patch to fix this bug. So when you edit settings, all cached blocks are invalidated.

@durifal

thank you for your contribution. Can you commit your changes to an issue fork and create a merge request?
This approach is more easier for project maintainer to review and at least commit the proposed changes.
thank you for your support.
