When using background setter, background text does not show correctly

[jposada202020]

When ussing the setter for background text, the text does not show correctly. I am assuming that this applies for anchor point setter, as I was receiving complains from the code that I was testing. However I thought it was my new PR. Did not test this for anchor_point.

So sorry for not to catching this before the Refactor, but normally I do all the test with list iterations. sorry @FoamyGuy .

Test Code

import terminalio
import displayio
from os import uname
if uname()[0] == 'samd51':
    import board
else:
    from blinka_displayio_pygamedisplay import PyGameDisplay
from adafruit_display_text import label
from adafruit_bitmap_font import bitmap_font

if uname()[0] == 'samd51':
    display= board.DISPLAY
else:
    display = PyGameDisplay(width=320, height=240)
splash = displayio.Group(max_size=10)
MEDIUM_FONT = bitmap_font.load_font("fonts/LibreBodoniv2002-Bold-10.bdf")



bitmap = displayio.Bitmap(4, 320, 2)
palette = displayio.Palette(2)
palette[0] = 0x004400
palette[1] = 0x00FFFF
tile_grid = displayio.TileGrid(bitmap,
                               pixel_shader=palette,
                               x=155,
                               y=0)
splash.append(tile_grid)

bitmap = displayio.Bitmap(320, 4, 2)
tile_grid = displayio.TileGrid(bitmap,
                               pixel_shader=palette,
                               x=0,
                               y=110)
splash.append(tile_grid)


text = "CircuitPython"
text_area = label.Label(MEDIUM_FONT,
                        text=text,
                        x=155,
                        y=155,
                        padding_left=10,
                        padding_top=10,
                        padding_bottom=10,
                        background_color = 0x990099,
                        padding_right=10)

splash.append(text_area)

text = "CircuitPython"
text_area = label.Label(MEDIUM_FONT,
                        text=text,
                        background_tight=True,
                        padding_left=10,
                        padding_top=10,
                        padding_bottom=10,
                        padding_right=10)
text_area.x = 155
text_area.y = 110
text_area.background_color = 0x990099
splash.append(text_area)


display.show(splash)

I have tested in Release 2.15.0 and works as expected, using the same code included

Good catch, I am glad you found this! I think this is the same issue from #49. I must have messed up the handling of background bitmap in refactoring. I will look into this tonight and get a fix in.
