Bug: Alpha slider disappears

Hello.

The issue I have is very simple. It is not critical, but just sort of annoying.

Whenever I open a color selector that does not support alpha (transparency), like, for example, choosing the colors of a spawn egg, and then I go back to the texture maker, the alpha slider stays gone so I cannot use transparency on my textures. Luckily, there is a simple workaround. Closing MCreator and reopening it and then going back to the workspace will bring the alpha slider back until I use another color selector that does not have alpha.

This can be a mild inconvenience as I like to go back and forth from making textures and making mod elements.
