Could you please look at remark lint issues and to cypress tests related with projects? (actions_projects)? They should not failed.

@dvkruchinin
Probably the tests in issues_prs and canvas3d_functionality should not be affected by this patch. It is not clear why them failed. Could you please take a look?

Sure. I`ll take a look.

No subset assigned?

[ActiveChooN]

It's a default value for the task without a subset.

[bsekachev]

Yes, just on UI we could rename it as we wish for better UX, right?

[bsekachev]

BTW, should not we paginate project tasks? Now it lists (and fetches from the server) all the tasks. It is probably inefficient. Another question is how to list such tasks considering several subsets.

[dvkruchinin]

I looked at it. This is similar to a situation that has already occurred (https://github.com/openvinotoolkit/cvat/pull/3001/files). In this PR, a horizontal scroll bar appears.

Remark lint failed due to empty bullet list items. I Will check other related test failures.

Yes, it's a good idea. And better way to do it on a server and just to order tasks by subset and filter by project, then cache responses on a client. But it looks like a separate feature.
