Error displaying with a mask

Hello Jani! I think I’ve found a bug in the latest version. it seems to me that when adding a mask to the arrow sensor, only numbers can be hidden under the mask. The segments remain uncovered. If you have added a mask and everything is fine, do not be too happy, because after copying the sensor or adding it to the container, the malfunction described above immediately appears. Thank you for your hard work.

Masking of the segments seem to work just fine for me, even after copy-pasting or moving to the container. Please provide step-by-step instructions on how to re-produce the issue with screenshots.
