When editing email templates via the visual builder, when setting the address for a web link it is no longer possible to use recipient variables as part of the URL. E.g on entering "https://%recipient.baseUrl%/docs/" as the address, the interface validation treats the URL as invalid and the "Apply" button is disabled (see screenshot).

At present the entire URL can be wrapped in % symbols, but it's no longer possible to have % symbols within the URL. I'm not sure why this feature was removed, perhaps it was a mistake in an update to the regex checking?

It's very useful to be able to do this. In my use case the email link directs a client to a specific web address at their (personalised) site, so it needs to be a combination of variable and text. Creating a separate recipient variable for every web address at the client's site would be very tedious, as the web page address varies from one email to the next (or even multiple times within the same email).
