&rgb_ug RGB_COLOR_HSB on split keyboard is not global when used within macro

[ivandaho]

When using using the example code as seen in https://zmk.dev/docs/behaviors/macros#layer-activation--more for Layer + Underglow Color, underglow color is only set for the central side of the keyboard during macro execution

• Color for peripheral side is unaffected by the macro
• If i change underglow color directly with &rgb_ug RGB_COLOR_HSB(86,81,85) outside of a macro, it changes for both sides as expected

Tested on main branch, built via docker method for Corne/NRFMicro
Unsure if any other &rgb_ug behavior is affected

reproducable in https://github.com/ivandaho/zmk/tree/corne-ivan, in case you have a corne/NRFMicro

• run ./buildcorne.sh in app directory
• flash firmware
• turn on LEDs by holding these buttons on the central/left side down in this order
  • leftmost button on bottom row
  • rightmost button on bottom row
  • "D" key (4th button on 2nd row)
• press either:
  • leftmost button on bottom row (central/left side)
  • middle button on bottom row (peripheral/right side)
