Describe the bug
Swapping between a dark and light them (or vice versa), does not use the correct dark/light icon packs. Instead, we must select the base theme first to load the correct icons, and then change the theme.
To Reproduce
Steps to reproduce the behavior:
- Set Burp's theme to
Light
- Select a dark theme in Burp Customizer, like
Dark Purple
- Navigate to Repeater.
- See that the icons in the top right are difficult to see, since they're made for a light background.
Expected behavior
Icon packs should be changed along with theme base.
