Non-Codicon Icons Hidden

[colin-grant-work]

Description

The conversion to Codicons in Theia 1.18 modified the CSS for side panels in such a way that masks, which were formerly the dominant mode of icon display, are no longer visible at all. This is a problem in this package, because the Memory Inspector icon uses a mask for display, and is currently invisible.

How to reproduce:

1. Start the application
2. Look for the Memory Inspector icon in the right sidebar.

Expected behavior

1. You should be able to see it, but right now, it's invisible.

I believe this should now be fixed with the latest version 👍
