Update 2021‑08‑10: The “stay in browser” feature introduced by Vivaldi 4.1 seems to be the solution to my problem in my very limited testing so far but it seems strange that this problem existed in the first place because it seems like opening a link in a native application instead of opening a link normally in the Web browser requires adding a special case/a conditional to the software so it seems strange that this special case was always enabled instead of being configurable at runtime from the beginning. Was the addition of this feature connected to this topic? I ask because the release that adds this feature came around twelve days after I posted this topic to request this feature. In any case, thank you for making this behaviour configurable instead of forcing it on all users.
