Alt feature doesn't work properly for MR with comments.

[ye11ow]

Sample output

test-pr 💬3  | href=https://github.com/ye11ow/noti/pull/3 color=green
-----
--Discussions (long long ago)
--ye11ow: test comment | href=https://github.com/ye11ow/noti/pull/3#discussion_r372215930
--ye11ow: Any comments on this approach? | href=https://github.com/ye11ow/noti/pull/3#discussion_r388745658
--ye11owAlt: no comments. Approved | href=https://github.com/ye11ow/noti/pull/3#discussion_r707825022
[Demo] Update unit test | color=white alternate=true

If this case, when Option key is pressed, the last item will replace the ye11owAlt line, not the original test-pr line.

This might be a bug of xbar itself.

Another native example that doesn't work:

title
---
item1
-----
--subitem
itemalt | alternate=true
