Fix sidebar infinite loop

[TaiWilkin]

Overview

When there's an error in the sidebar, it attempts to catch the error and reload the sidebar. Assuming that the error isn't transient, this causes an infinite loop of error -> reload -> error -> reload -> etc., which results in the page freezing.

Expected Behavior

The error should be caught and handled. Errors should not cause the page to freeze.

Actual Behavior

The page freezes.

Steps to Reproduce

• Raise any error in the sidebar to replicate locally.
