Spacer nodes edit size boxes in dashboard 2 have all turned blank

Clicking or double clicking the box does nothing. I’m running v4.1.0 on a Raspberry pi 5. All software is currently updated. Any ideas on how to fix this?

nodejs v20.19.5

Operating System: Debian GNU/Linux 12 (bookworm)
Kernel: Linux 6.12.34+rpt-rpi-2712

Could this be related? Node-red dashboard layout non-editable

I am seeing this too, I haven't manually configured spacers before so don't know if it is a change from previous behaviour.

They can still be resized successfully using the visual layout editor.

I think this was a bug introduced in flowfuse dashboard 1.26.0
