Issue when using same calendar but different color on multiple Screens/Blocks

[Dan-Peck]

Under certain specific conditions, calendar colors may "flip-flop" between colors when their content refreshes. Those conditions are:

• More than one concurrently active Screen or Block is showing events from the same calendar source
• AND the color selected for that calendar source is different between the multiple Blocks

For example:

• One calendar block is set to "Auto" color
• The other calendar block is set to a specific (i.e, "Autumnal") color
• Both Blocks are displaying on a Screen(s) at the same time
• Now, depending on when refreshes take place, the color on either calendar block could be either one of the "Auto" -or- the "Autumnal" colors rather than the color selected in its own block configuration
