GUI textures which fail to load do not produce errors in the output log

May be the reason why MC-299048 happens, also how can I stop the new software from automatically turning IDs into massive disruptive links?

When the game fails to load most textures, an error is produced in the game logs, however for some reason this does not appear to affect user interface textures.

A resource pack is attached to test this, which unloads the budding amethyst, enchanted weapon hit, and highlighted button textures. The former two correctly produce errors in the game log about a texture being missing, however the button texture does not. It’d be expected that all three would cause log errors to be shown.
