Pressing super+space does not launch ilia

• [ x] I've read the Regolith documentation and didn't find any relevant topic

Describe the bug
When super+space is pressed, the application launcher (ilia) should be launched. However, nothing happens. In fact, any keyboard shortcut that contains space, such as super-shift-space (command) or super-alt-space (file search) does not launch. Other keyboard shortcuts that do not contain space work ok. I can even map something like super+x to ilia, and it launches ok. But super+space does nothing.

To Reproduce
Steps to reproduce the behavior:

Press super+space

Expected behavior
A clear and concise description of what you expected to happen:

The Ilia launcher should pop up.

Screenshots

Additional context
I tried running ibus-setup and deleted the "Next input method" entry which contained super+space, and rebooted to see if it would fix the issue. However, that did not fix it. I have 2 input keyboard sources: en-us and in+san-kagapa enabled.

I also ran xev -event keyboard and this is the output when I press and release super+space:
