Issue was around experiment targeting which has been updated.

I have verified that this issue is no longer reproducible with the latest Firefox Beta (86.0b7 Build ID - 20210207185447) and the latest Firefox Nightly (87.0a1 Build ID - 20210209092956) installed on Windows 10 x64, macOS 10.15.7, and Linux Mint 20 x64. Now, I can confirm that the "Set as Default" infobar and the old "Set Firefox as Default" modal are not displayed at the same time.
