Tasks plugin nested tasks render incorrectly with show tree on wide windows

[Akilaydin]

Summary

When using the Obsidianotion theme with the Tasks plugin, nested tasks rendered with show tree are misaligned.

On wide windows, child tasks are pushed too far to the right and there is extra spacing between the parent task and the first child task.

Steps to reproduce

1. Enable Obsidianotion.
2. Enable the Tasks plugin.
3. Create nested tasks.
4. Use a Tasks query with show tree.
5. Make the window wide.

Example of the code:

'''tasks
not done
show tree
hide backlink
'''
