[DateRangeInput2]: footerElement prop does not render

[fnziman]

Environment

• Package version(s): "@blueprintjs/core": "^4.7.0",
  "@blueprintjs/datetime": "^4.3.4",
  "@blueprintjs/datetime2": "^0.5.0",
  "@blueprintjs/popover2": "^1.5.0",
  "@blueprintjs/select": "^4.5.2",
  "@blueprintjs/table": "^4.5.0",
  "@blueprintjs/timezone": "^4.4.4",
• Operating System: MacOs Monterey 12.1
• Browser name and version: Chrome Version 104.0.5112.101

Code Sandbox

Example

Steps to reproduce

1. add footerElement prop to DateRangeInput2
2. ensure that it does not render

Actual behavior

No footer component rendered

Expected behavior

Render footer component

Possible solution

It seems that the prop is not used at all by DateRangeInput or by DateRangeInput2. Both DateInput and DateRangeInput, do render it. I think it just needs to be added
