Long pack names and world descriptions don't stop with "..." in some menus

Confirmed in 1.16 Pre-release 8.

The ... symbol is now used by data packs and resource packs in later snapshots although it does not work properly.

The bug should be assigned to the UI category.

Confirmed for 1.16 RC-1. Please keep it all in one text.

The description should be changed to the following below or similar to make it look cleaner:

The bug

When a pack name or world description is too long, it continues to go to the right of the screen even beyond the scroll bar instead of stopping with a ... symbol.

I am unable to reproduce this issue in the resource pack folder, however am I able to reproduce this in the single player world list (in 20w51a).

Can confirm in 21w03a for single player world list.

Can confirm this was fixed for resource packs and data packs in 20w30a. The world selection screen issue is MC-383.
