Description

There seems to be a bug with the gradient markers and the HEX input field.

How can we reproduce this bug?

1. [Add a Gradient]
2. [Click on a Gradient Marker]
3. [Click in the HEX Input Field (below saturation field) and add a custom color (copy and paste does not work) or manually]

What did you expect to happen?

This should update the gradient marker and the gradient color string.

What happened instead?

It removes the gradient string from the picker and only adds the single color.
