[4.7] When trying to pick use slider in color picker it will automatically close

I have pulled latest version from github.

Reproduction.
Open any blueprint.

Add Linear Color variable.

Save. (just in case).

Open Color picker, try to use slider to adjust alpha color, or the side sliders, to change color.

Color picker closed.

Yup, I have same issue

Hey iniside and zeOrb -

Can you confirm that the exact CL number of your GitHub version is? Please also if possible since the 4.7 Branch in GitHub is not the same as the Launcher Preview builds, test on the Launcher and see if you have the same issue.

In the meantime, I will continue to test here.

Thank You

This is last commit I pulled today:
55b43d6 (at least I think it last)

Or here is range:
f5837dc…55b43d6

And the issue is still here. I will try to test with binary preview later.

Hey iniside -

Thank you for the additional information, it helped me track down the issue and it appears to be fixed in our internal master branch of the engine. I am working with our leads to make sure that the fix is applied to our release 4.7 branch as soon as possible.
