Edit Task modal sometimes fails to create all IDs when adding several dependencies

[claremacrae]

⚠️ Check issue is valid.

• My request is about the Tasks plugin for Obsidian.

⚠️ Check that this issue hasn't been reported before.

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

Steps to reproduce

1. Create a note with the following content

- [ ] #task -9 days ⏳ 2024-12-21
- [ ] #task -8 days ⏳ 2024-12-22
- [ ] #task -7 days ⏳ 2024-12-23
- [ ] #task -6 days ⏳ 2024-12-24
- [ ] #task -5 days ⏳ 2024-12-25
- [ ] #task -4 days ⏳ 2024-12-26
- [ ] #task -3 days ⏳ 2024-12-27
- [ ] #task -2 days ⏳ 2024-12-28
- [ ] #task -1 days ⏳ 2024-12-29
- [ ] #task 0 days ⏳ 2024-12-30

2. Put the cursor on the 0 days (middle) task.
3. Run the command Tasks: Create or edit task
4. Click in the Before this field and select -9 days
5. Click in the Before this field and select -8 days
6. Click in the Before this field and select -7 days
7. Click in the Before this field and select -6 days
8. Click Apply

Expected Behavior

• All 4 chosen tasks have a new ID value.
• And 0 days has a depends on value of all 4 of the new IDs.
• Editing the 0 days task again should show all 4 of the added dependencies:
  

- [ ] #task -9 days 🆔 zrnvys ⏳ 2024-12-21
- [ ] #task -8 days 🆔 ebxr1s ⏳ 2024-12-22
- [ ] #task -7 days 🆔 jio0x7 ⏳ 2024-12-23
- [ ] #task -6 days 🆔 ylrplh ⏳ 2024-12-24
- [ ] #task -5 days ⏳ 2024-12-25
- [ ] #task -4 days ⏳ 2024-12-26
- [ ] #task -3 days ⏳ 2024-12-27
- [ ] #task -2 days ⏳ 2024-12-28
- [ ] #task -1 days ⏳ 2024-12-29
- [ ] #task 0 days ⛔ zrnvys,ebxr1s,jio0x7,ylrplh ⏳ 2024-12-30

Current behaviour

• Some errors are usually displayed:
  
• And usually at least one task is missing a new ID value.
• Editing the 0 days task shows one of the requested dependencies was not added:
  

- [ ] #task -9 days 🆔 zrnvys ⏳ 2024-12-21
- [ ] #task -8 days 🆔 ebxr1s ⏳ 2024-12-22
- [ ] #task -7 days ⏳ 2024-12-23
- [ ] #task -6 days 🆔 ylrplh ⏳ 2024-12-24
- [ ] #task -5 days ⏳ 2024-12-25
- [ ] #task -4 days ⏳ 2024-12-26
- [ ] #task -3 days ⏳ 2024-12-27
- [ ] #task -2 days ⏳ 2024-12-28
- [ ] #task -1 days ⏳ 2024-12-29
- [ ] #task 0 days ⛔ zrnvys,ebxr1s,jio0x7,ylrplh ⏳ 2024-12-30

Which Operating Systems are you using?

• Android
• iPhone/iPad
• Linux
• macOS
• Windows

Obsidian Version

1.8.0

Tasks Plugin Version

7.14.0

Checks

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

Possible solution

I believe that the code is writing one task at a time, so potentially 5 writes in quick succession in this example.
And Obsidian does not always keep with updating its cache.

Ideas:

1. Changing the file-writing code in File.ts to use vault.process() might help:

const fileContent = await vault.read(file); // TODO: replace with vault.process.

2. Try to rewrite all the tasks in the file on one go, instead of one write per task being edited
3. Consider using mnaoumov/obsidian-dev-utils for all file reading and writing processes.
