Unify how macOS online installer behaves from keyboard after entering Qt Account credentials. At least I intuitively press enter after entering Qt Account login information. Same applies even if I have pre-filled credentials.
On Linux and Windows online installer 4.1.1 and 4.2.0 goes to next wizard page (same as press Next button, which is expected action from my point of view).
On macOS online installer 4.1.1 doesn't react at all. The online installer 4.2.0 installer opens Sign up -page from the installer (couldn't figure out how get to previous page and need to restart the installer to continue).
Recommendation: change default focus to Next -button on macOS as well.
