Prevent keybinding settings link to keymap file from opening multiple duplicate tabs

[Zoooook]

Summary

From the keybindings settings page, at the top it says “You can override these keybindings by copying and pasting them into your keymap file”, where the last 3 words are a link to a keymap file. When I copy a keybinding and click the link to the keymap file, and then go back to copy another keybinding, and click the link again, it opens a new instance of the same file in a new tab. I would like to prevent this behavior and just open the existing tab.

Motivation

Duplicate tab proliferation is annoying when all I'm really doing is navigating between 2 settings pages.
