This deduplication helps with readability.
Pass get_topic_key in recent_topic_row instead of
computing it in DOM.
Fix broken test_update_unread_count
after this change. This was a regression
which went unnoticed.
We store the relevant data to hide/show a topic in the row itself,
and use jquery to hide/show it on filter change.
This also fixes search breaking the set filters.
We reuse the existing logic for displaying and updating stream color
from the stream left sidebar.
Tests fixtures were extracted and updated for this commit.
* Add action to mute topics.
* We don't need to store muted data per topic as previously planned.
* Moved launch topic test to the top so that they run on non-modified
data.
