Gradients break when attempting to preview a theme⁠›››

If you have a gradient on a label instead of a solid color, attempting to preview the theme through the theme editor by using the Start button turns those labels into a solid color at #00FFFFFF when you stop previewing. I haven't tested this with widgets or subwidgets yet, just labels. Version 1.41.0.0

This should be fixed in the next stable release. Thanks!
