Generally, tooltips placed at top look good. If the tooltip cannot
fit at top, it will by default be placed at opposite side.
Removed the unnecessary top placement definitions.
Here, the tooltip was partially visible. This bug was similar
to the one that is corrected for recipient bar icons.
I have removed the class attribute `tippy-zulip-tooltip`
for Filter stream title as this will be handled by the
new changes.
This commit migrates the `left_sidebar.html` Django template
to handlebars by creating a new file as `left_sidebar.hbs`
which is then rendered using `ui_init` module.
These are the minor changes introduced by virtue of template
migration -
- The `compute_show_invites_and_add_streams` function now
only concerns with the invite_to_realm_policy.
- Renamed the `compute_show_invites_and_add_streams` function
to `compute_show_invites` due to the above change.
- Fixes relevant `test_home.py` tests due to the above
changes.
Fixes part of #18792.
