Describe the bug
When I add a new comment on a card, the counter on the card is not being updated. In combination with the Client Push app, this results in comments not being updated on other devices until a page reload. Interestingly, if the commenter reloads the page, the content (including comments and the counter on the card) gets updated on all devices.

This is a regression which came with some recent update of NC or Deck.

To Reproduce
Steps to reproduce the behavior:

1. Go to a deck
2. Click on a card
3. Add a comment to the card

Expected behavior
The counter of comments on the card should change (+1).

Actual behavior
The counter doesn't change until a page reload.

I tested some more, and it's not necessary to reload the page. It's enough to switch to another tab and back to the NC-tab to update the comments counter on the deck and (I assume) consequently the comments on any other machines when using the Client Push app. This behavior is consistent on different Browsers (Firefox, Chromium) and OSs (Fedora 40, Windows 11).
