Exactly as the title says, using the quick edit to modify BIT columns of any length doesn't work using the quick edit, however you are able to modify the value if you click on the "Edit" button for that row and do it the normal way. With the quick edit, you get the following error:
0 rows affected.
Warning: #1264 Out of range value for column 'bit_test' at row 1
Tested using versions:
4.2.0-dev
