Hello :hanna_a,

I have verified the other spotlights as well and have noticed the same issue on the ones that have the following ids:

• AI_WINDOW_TOU_EXISTING_USERS_MODAL
• BROWSER_BACKUP_OPTIN_SPOTLIGHT
• CONTENT_TILES_TEST
• MULTISTAGE_SPOTLIGHT_MESSAGE

I have also attached a zip file that contains screenshots of said spotlights.
Please let me know if there is anything else needed.

Appears to be a DUP of bug 1996900, and there are other vertical misalisngment buttons as well. Current guess is that this is related to moz-button itself and the Nova restyling.
