Status Effect on the HUD doesn't show up anymore

When getting effects, the status effect badges in the top right of the HUD don't show up anymore. The effects are applied, their particles appear, and the Mob Effects control (default Z on keyboard) displays them with their remaining times. It's just the badges that are missing.

Steps to reproduce:

1. Enter any world and get into Creative mode.

2. Execute an /effect command, e.g. /effect night_vision 600.

Expected results:
The night vision effect badge appears in the top right corner of the screen.

Actual results:
No effect badges appear, but if you press Z on the keyboard the Night Vision effect is listed in the panel.

Additional information:
Active status effects should be evident from their badge appearing on the HUD, from their particles ("bubbles") attached to the affected player, from their presence in the Mob Effects panel, and from changes the effect makes to the player experience. This report only covers the missing HUD badge, but other recent reports exist that describe apparent problems with particles and/or player experience changes not happening or happening at the wrong time. Only the Mob Effects panel appears to reliably report the status effects currently applied, so don't become confused if the other bits of evidence seem inconsistent; other unfixed bugs may be causing this.
