... the setting jumps back to the last choice.
Steps to reproduce the problem (Firefox 69.0.1 64 bits here, under Windows 10 Home Edition 64 bits):
- Choose "APs of length 28 or longer" in the drop down list
- Click the "Submit" button and you will get a list of such APs (certainly an empty one)
- Choose "All APs"in the drop down list
- Click the "Submit" button: the selected option in the drop down list goes back to "APs of length 28 or longer" and the list is not updated to "All APs"
I have to choose "APs of length 20 or longer" to get back a full list of APs.
