Context

We're trying out using nested linked content tabs on our open-source mirror help page as a replacement for switches (e.g. distro release, file format). An example can be found on our Debian help page (https://38b0fed1.ustcmirror.pages.dev/help/debian).

Bug description

When linked content tabs are nested, their border-bottom behaves erratically when they're activated while invisible.

See the demo below.

It doesn't impact any functionality, just a minor cosmetic problem.
