I just noticed a bug with pushing and popping tags and splitting windows:
1. I have one window open, zoomed in.
2. I push a tag with push-tag to go to a function definition.
3. Then I split the window in to two windows with hsplit-window.
4. Then I pop the tag to go back to my original location with pop-bookmark.
I expect just the active window to go back to the original location, with the other window remaining on the function definition. However, both windows go back to the original location. Now that they're split, if I push a tag and then pop a tag in a window, only that window is affected.
