Fix permalink discussion note being collapsed
What does this MR do?
Permalinked MR discussion comments will no longer collapse.
What causes the bug?
The notes tab panes(
.notes.tab-pane) is hidden initially until it gets a
.active class after the JS kicks in
merge_request_tabs.js.es6 -> Contstructor -> activateTab
Previously, if there was a hash in the URL,
#notes_xxx, we were clicking the toggle button if the area was hidden,
toggler_behavior.js; which even though the discussion is expanded in the server-side render, is actually considered hidden because the hidden notes tab parent,
Summary: If the notes tab doesn't become visible in time, then we click the toggle button which hides the linked discussion. race-condition
You can see the behaviors(
toggler_behavior) get required higher up in the bundle than the
toggler_behaviour runs inside a jQuery ready while
merge_request is just in an IIFE
Are there points in the code the reviewer needs to double check?
