FontSmoothingType LCD produces wrong color when transparency is used

ADDITIONAL SYSTEM INFORMATION :
Tested on Linux and Windows, with Java version 8u361 and with Java 20.1 and JavaFX 20.1

A DESCRIPTION OF THE PROBLEM :
When a colour with transparency is used, FontSmoothingType.LCD produces the wrong colour

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Run the attached code and compare the colour of the Text nodes with the colour of the border

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The colour of the Text nodes should be the same as the colour of the border, independently of which FontSmoothingType is selected
ACTUAL -
When FontSmoothingType.LCD is selected, the color of the Text nodes is wrong
