## Problem
On pages that needs to check conditions for which data is loaded
asynchronously, the navigation links in the sidebar appear disabled for
a split second:
<img width="1394" height="1636" alt="image"
src="https://github.com/user-attachments/assets/0681966d-676d-4c8c-8bd4-852dcf93ddb7"
/>
## Solution
Check whether the required data is loading and override the styles so
that the links are still disabled to avoid errors but appear as normal.
## How to test
- Open the project setting page
- Check the styles of the sidebar items carefully while it load (might
require to refresh a few times to be sure)
