Button Fix (MC-259387)

A small client-side mod that fixes widget focus issues in any in-game GUI.
These issues affect all Minecraft versions since 1.19.4.

In Vanilla, GUI buttons and sliders remain focused after a mouse click until another widget claims focus. This can be visually distracting - especially when using resource packs that change the appearance of GUI widgets.
Button Fix resolves this issue by properly resetting the focus after interaction.

This fix applies to all sliders and pressable widgets in in-game GUIs - for example, the recipe book button in the inventory screen, or the buttons and sliders in the main menu, pause menu, or mod config screens - as long as they use vanilla widget implementations.
