[24.0] Fix saving user preferences crashes tab

[ElectronicBlueberry]

fixes #17862

The cause was a computed setter triggering an infinite loop.

The computeds getter was getting a bool value, while it's setter was toggling the value (not setting it)

In combination with a library component which was triggering the setter on getter changes, this caused an infinite loop when the bool value was set to true via code after component mount.

Due to this value being linked to UI components conditional rendering and the local storage, this rapid self-toggling quickly crashed the tab.

The intermittency that I've seen was likely due to cleaning local/session storages while experimenting. But I did not make the step to activity bar. Thanks for solving this @ElectronicBlueberry!
