Steps to reproduce this are pretty simple. On the Blazor Wizard demo at this link:
- Enter a password on step 1
- Click 'Next' to bring you to the 'Shipping' step
- Set focus to the 'City' input box. I clicked to the end of the default string that is pre-populated as 'Torino'
- Press the left arrow key. This sends you back to Step 1 (Registration)
This is a pretty big stumbling block for using the Wizard component, but I may be missing some kind of setting or code that will resolve this.
