Will a sram 11 speed front derailleur work with 10 speed shifter?

I realized that the front derailleur is Shimano Ultegra but the rest of the groupset is SRAM Red. 2x10. The internet told med that mixing and matching brands like this will not work (in all cases).

Front derailleurs are friction shifting, not indexed, so they are largely compatible with other brands.
