The "underline" color does not change...

[jigarj]

In the bootstrap-wysihtml5 editor, the color of "underline" doesn't change to new color: Here are the steps to reproduce the issue:

1. Enter text
2. Underline text by pressing "U" button.
3. Select all the text and apply "blue" color from the color button.
4. Both text and underline are changed to "blue".....so far so good!
5. Now, change the color of text & underline to a different color e.g. "red"
6. The color of text changes to "red"
7. The color of Underline still remains "blue".

In step 7, color of underline must change to "red".
