web: Fix blob view border
Created by: umpox
Description
Changes the border around the blob/tree view from targeting the first div to being applied to the relevant elements.
This fixes a few bugs I noticed when a different div element was inserted before the code (e.g. the tour info, an alert, etc)

Test plan
Tested locally by navigating directly to a blob view and enabling different states.
