Dropdown with label draws a frame

How-to
1

I have a dropdown from type LV_IMG_SRC_SYMBOL where a rectangle frame around the symbol area is drawn. This happens in the lv_dropdowns.c file (v8.3.3) where the lv_draw_label is called.

Is it possible to avoid this frame without to adapt the lib code?

LV_USE_FONT_PLACEHOLDER can switch off the drawn rectangle.
