Edit Task modal: creating a task with both Cancelled and Done is possible

[ilandikov]

Please check that this issue hasn't been reported before.

• [X] I searched previous Bug Reports didn't find any similar reports.

Expected Behavior

The Modal should not let create a task with both Cancelled and Done dates set - the Apply button should not be accessible

Current behaviour

The Apply button is normal and a task with Cancelled and Done date is created

Steps to reproduce

• Create a task (- [ ] blabla)
• Set cursor on the task
• Open Edit task modal
• Input valid dates in Done and Cancelled fields
• Click Apply

Which Operating Systems are you using?

Obsidian Version

1.6.7

Tasks Plugin Version

7.6.0

Checks

• [ ] I have tried it with all other plugins disabled and the error still occurs

Possible solution

Make the Modal disable the Apply button when both Done and Cancelled date are present.

I have a compact one-line fix for this but, is it testable only manually due to the architecture of our modal. An improvement on that matter can be made, but that is another topic.
