Unable to bind Float variables to certain properties in Widget elements

Unable to bind float variables to certain properties in Widget elements. You are able to bind Structure floats if needed as a workaround.

Repro Rate: 3/3

Tested this in //UE4/Release-4.27 @ CL#18319896 and I was able to bind float variables to the percent property of the Progress Bar, it is a regression!

1. Create a new blank Blueprint project.
2. Right-Click in the Content Browser and create a new Widget Blueprint. (User Interface/Widget Blueprint)
   • Select the User Widget as the Root Widget during creation.
3. In the Designer view, place a Progress Bar down utilizing the Palette.
4. S.witch to Graph and create a new variable of type Float
5. Compile & Save the Widget Blueprint
6. Back in the Designer view, click on the Progress bar.
7. In Details under Progress, select the "Bind" dropdown to the right of Percent.

Results: User is unable to bind the newly created float variable.
Expected: User is capable of binding the float variable to the percent property of the Progress Bar
