minBarLength option is broken

[Jurkovic]

Hello there. Dataset option minBarLength seems to be broken. Top border of bar element is not rendered at all and tooltip of such a bar element seems to be misplaced. This is really nice option to achieve zero values compensation especially when _model was removed in chartjs 3.

Expected Behavior

Top border of bar element should be properly rendered and tooltip should be placed to the top of the bar element (I'm not sure if this was intention or if it is bug)

Current Behavior

Top border of bar element is not rendered when using minBarLength with some borderWitdth. Also tooltip is placed to the center of x label.

Steps to Reproduce

Context

For purposes of my project, this should work correctly in order to indicate difference between zero value and no data states.

Environment

• Chart.js version: 3.4.1
• Browser name and version: Google Chome 91.0.4472.114
