Missing variable: zindex-tooltip

54311e5 introduces the $zindex-tooltip variable that is undeclared elsewhere.

I believe this is set by bootstrap

It is going to be properly replaced at build time to 1080 px. I agree that it should likely have a bs- prefix to figure that out.

Yes this is indeed coming from bootstrap and is replaced at compile time.
Since this is not pre-pended with a bs- and if you think it's worth for clarity, adding a comment about this would be ok.

Thanks for the clarification. This broke the compilation of the Scientific Python Hugo Theme, so I suppose it's the first bootstrap variable used this way. I can custom-define it for our theme.
