RGB strip turns on before color change? (old color shows briefly)

I’m seeing an issue with turning on an RGB strip through an automaton. It seems as if Home Assistant is commanding the Tasmota controller to turn on, and then commands it to change the RGB color. For example, if the LEDs were previously red, and my automaton is set to turn them on in blue, the LED strip will turn on and will briefly be red before switching to blue.

Might there be a configuration issue here?

The YAML for the action is quite simple:

service: light.turn_on
data:
  rgb_color:
    - 0
    - 255
    - 0
  brightness: 255
target:
  device_id: 40a85e67fae76f87c908595877b90e34

I’ve tried to work around this by adding an initial command to the light to set a different color at brightness 0, followed by the same color at brightness 255, but that does not help.

Thanks!
