Subtasks not hidden by "Hide Tasks Details" feature

[SaiKiru]

Describe the bug If I try to hide all tasks details, only the main tasks are hidden. The subtasks remain "opened" or their details are not hidden.

To Reproduce Steps to reproduce the behavior:

1. Go to any project
2. Add some tasks
3. Add some subtasks
4. Hide tasks details with CTRL + H or the option in the utilities in the upper right

Expected behavior ALL tasks will have their details hidden.

Screenshots Before hiding details:

After hiding details: After hiding details

Desktop (please complete the following information):

• OS or DE: Pop!_OS 21.04 - GNOME 3.38.5
• Version 2.7

Additional context I tried using both the flatpak version and compiling the source.

It is a strange behavior, but valid, the solution could perhaps be to add a new button that closes the subtasks
