'show tree' does not update its results if parent list items are edited (and likely if the parents are tasks not matched by the search)

[claremacrae]

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

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

Steps to reproduce

1. Create a note called 'Heading Edits'

2. Paste in this content:

   - Other
       - [ ] #task Cash for admission
   - Clothing
       - [ ] #task Costume
       - [ ] #task Goggles
   - Changing
       - [ ] #task Towel
   
   ```tasks
   path includes {{query.file.path}}
   
   group by function task.parent?.description ?? ''
   ```
   

   • Note that the group by function code groups the tasks by their parent list items

3. Arrange view so that you can see the file in both Source mode and Reading mode, like this:

   

4. Change the Other list item to 1 Other

Expected Behavior

The search results should be updated to show the renamed (and re-ordered) heading.

Current behaviour

The search results do not update until the Reading mode file is closed and reopened - or the vault reloaded.

Which Operating Systems are you using?

• Android

Obsidian Version

1.7.4

Tasks Plugin Version

7.12.1

Checks

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

Possible solution

The relevant code is Task.identicalTo() and ListItem.identicalTo()

The problem is that Tasks is checking to see if any tasks have been edited.
But it is only checking the children of the tasks that are displayed, and not their parents.

Things to consider in the implementation.

• the parent may be any of:
  • null
  • a list item
  • a task line that has the global filter (if set)
  • a task line that does not have the global filter, so is ignored by Tasks
• the parent may have been edited to change between any of the states listed above, such as converted from a list item to a task
• the immediate parents may be the same, but the parents of the parents may have changed, for example
