& not passed as arg when using Navigation feature

[H4irBear]

Hi, this is a bit of a weird one. I am passing a URL to firefox which contains a bunch of & characters. This is an example:
https://www.google.com/search?rlz=1C1GCEJ_enES1026ES1026&lei=SJs9Y5XqLMOQxc8P1MSwqAY&q=speed%20test&ved=2ahUKEwiVrsrVrMn6AhVDSPEDHVQiDGUQsKwBKAB6BAhbEAE

When I pass it using the context menu it works, however when I pass it using the Navigation feature, the URL beyond the first & is truncated. I have tried the setting to enclose args in ", however the result is the same.
