Nested linked content tabs have strange border-bottom behavior

[iBug]

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.

Thanks for reporting! Oh, I love it when those kinds of errors are reported that lie deeper below the surface – it shows how far we've already come in 8 years, but also how far we still have to go 😅 Fixed in 2d07a6a.

The problem also manifested without content.tabs.link, as the active tab was not correctly computed.
