back to Top link is hidden behind title, when it is targeted

[pcarvalho]

When using the toc to navigate to sections, the titles are applied this:

.toc-heading:target {
    position: initial;
    [...]

which make it cover the "Top ↑" link. By removing or changing it to

position: initial

, the link is now clickable again.

This change seems to be introduced here: https://meta.trac.wordpress.org/ticket/2793

example: ​https://developer.wordpress.org/reference/classes/wp_query/#status-parameters

Steps to reproduce

1. click on any entry in the TOP
2. Try to go back to top by clicking on "Top ↑"
