The cursor doesn't appear on address bar after creating new tab (after the latest Nightly update)

After Firefox Nightly's latest update (80.0a1 (2020-07-11)), when you open a new tab (ctrl+t), the cursor does not appear on the address bar. Hence you cannot type an url right away. You have to first use the mouse to click on the bar which is very inconvenient. That only happens when the Speed Dial extension is enabled.

Other than that, keep the good work guys, Thank you.
