When activating Spectator mode in a world, I was asked if I want to enable it or cancel.  Instead of the buttons showing "Keep original settings" and "Turn on Experiments anyway, they both show "hbui.CreateNewWorld.experimentalFeatures.ao...". The "..." is meant to be a continuation of it, since it cannot fit on the button.

Steps to reproduce:

1: Open Minecraft Preview.

2: Go to the "Experiments" tab in the Create World Screen.

3: Enable one of the experiments and look at the message of the pop-up.
