Issues setting a task status to done when multiple viewports show it

[alvaromartin]

I'm running into an issue where I can't set a task to done using <Leader>td when it's present in multiple viewports in the same file. See the gif below:

Steps to reproduce

1. Create a viewport "Test Tag | +test"
2. Create a viewport "Test"
3. Add a task "test task" inside of "Test" viewport
4. Modify the "test task" task using <Leader>tm and add "test" tag using +test
5. Save the file :w<CR>
6. Both "Test Tag" and "Test" viewports display the task "test task"
7. Place cursor on "test task" inside of "Test Tag" viewport and set it to done using <Leader>td
8. Save the file using :w<CR>

Expectation "test task" is set to done in both "Test Tag" and "Test" viewports
Actual Result "test task" is not set to done at all. It only works when I set it to done in the "Test" viewport

This is probably the same as #113, #176. There's even a proposed fix but I think it may have some unintended side-effects which is why it hasn't been merged yet.

(I haven't looked at the code for over a year so I hesitate to comment on what a good solution would look like. Just summing up the situation.)
