Reloading resource packs via hotkeys while no-HUD view is active results in loading screen being half resolution

When no-HUD view is active (default toggle key: F1) and resource packs are reloaded via F3+T, the loading screen that appears will be at half resolution, covering only 1/4 of the screen.

Attached is a sequence of the screen as it progresses in normal view (expected) and as it progresses in no-HUD view.
