there is a bug in "printFixedPgm"

Code:

static const char text[] PROGMEM = "PROGMEM Text";

static void textDemo() { display.setFixedFont( ssd1306xled_font6x8 ); display.clear(); display.invertColors(); display.printFixed(0, 32, "Inverted bold", STYLE_BOLD); display.printFixedPgm(0, 40, text, STYLE_BOLD); display.invertColors();

} on Display PROGMEM Text is white: 20240205_085617
