Copying the BBB Link copies the set nextcloud design color

[Averageunknownuser]

Hello everyone,

when we copy a BBB room link, we copy the link with the set nextcloud design.

It seems like the " /settings/admin/theming " built in design feature causes the problem.
Currently we have the Color #0A2340 as our primary color.
And if we copy the BBB Link we do copy the set color theme aswell. It doesn't matter which color you are using as primary set color theme.

A clear and concise description of what the bug is.

To Reproduce
Steps to reproduce the behavior:

1. Go to settings
2. Set a color theme (e.g blue)
3. Go back to the BBB app and copy your link
4. Go to Outlook and create a new email
5. Paste your copied link in your new mail

Expected behavior
After pasting the link in your new mail the link will not be readable
