[4.7.6] LinearColor default value is handled incorrectly after removing a link

Build: 4.7.6, built from source

Description: When looking at the default value of a linear color parameter after removing a link in the blueprint the color picker shows R=0,G=0,B=0,A=1 (ie. black) - but the actual value seems to be R=G=B=A=0 (ie. invisible).
This problem also occurs when using a set node for a LinearColor variable.
Restarting the editor seems to fix the issue in some cases but not all (especially variable assignment).

Repro Steps:

  1. Print text to screen
  2. Connect & disconnect the color pin
  3. Start game, wonder why text is gone
