Question TMP Text Masking Issue

Hello! I was utilizing a TextMeshPro Text GameObject for my Unity game when I suddenly encountered a peculiar error. On the TMP docs, it states that the Masking setting of the Overflow box on the TMP Text component will make it so all text outside of the box's boundaries will be masked to users. However, when I select the feature, it does... nothing. It seems that this is a known bug, however, and has been for many months now. Is there anything that the Unity community could assist me with regarding this issue, and is there a work around embedded in TMP?
