Looks good to me.

I think your findings posted in the issue are correct.

Tested the solution from PR branch successfully with:

Adafruit CircuitPython 8.0.0-beta.0 on 2022-08-18; Adafruit PyPortal with samd51j20
Board ID:pyportal

In case it may be helpful in the future, here is the test code I used to verify the issue and fix:

import time
import board
import terminalio
from adafruit_display_text import bitmap_label

text = "Hello world"
text_area = bitmap_label.Label(terminalio.FONT, text=text)
text_area.x = 10
text_area.y = 10

text_area.label_direction = "UPR"
text_area.label_direction = "UPR"  # second time we set it causes trouble

board.DISPLAY.show(text_area)

val = 0
while True:
    val += 1
    text_area.text = f"Hello World {val}"
    time.sleep(0.3)
