Tabbing out of password field not working?

I have a few sp-textfields on a login page and noticed I am unable to tab out of the sp-textfield of type password. Any ideas on how I could get around this? Tabbing seems to be fine on all the other sp-textfields.

thanks!

Interesting, I am also seeing the same issue in the Kitchen Sink UXP sample project.

Sounds like a bug. Ping @kerrishotts
