Steps to reproduce:
1. Have at leat two swatches in the swatches panel. The 1st with, for instance, 20% tint and the 2nd with 100%
2. Type some text and select, then apply the switch with the 20% tint.
3. Then apply the other swatch.
Result: the text isn't display in the color of the 2nd swatch, because the tint is not changed to 100%
