fix: disable app list lag issue

[phlpsong]

List item views may refresh after selection changes. This change will prevent content refresh after each selection.

After select too many apps in the list, you may experience significant lag behaviors.

@CanglongCl This will revert some changes in #340, please kindly check it. Any questions or suggestions, please let me know.

I tested this code, it doesn't fix on my mac.

I actually tried the previous workaround #346 (comment) in SwiftUI and it worked, although it's not elegant.

If possible, you can try to find out the specific reason.

To clarify, this is not a fix for #346.

You could reproduce this issue by:

1. Click + to open app importer
2. Select some apps, maybe 10 above
3. Switch the tab or select the apps

you may experience the list lag sometimes

Sorry, I misunderstood.
