Steps to reproduce the behavior

In stackblitz it works fine. Download the project and run it directly to reproduce.

1. Use TAB key to focus calendar component, calendar popup is opened.
2. Press TAB key again - nothing happens and focus is still in the input.

If Froala editor is not present in the form, it works fine. Remove it to see expected behavior.

Expected behavior

When calendar input is focused and you press TAB key, focus jumps to popup.

I'm aware that there's a possibility that Froala editor code hijacks the global keydown events, but I wasn't able to trace the exact reason. I'm hoping you could confirm if there's no option to mitigate it on primereact's side.
appendTo: "self" helps with the issue but I cannot use that as my Calendar is displayed in the table and it's cut with this setting.

Start by downloading the linked StackBlitz project and reproducing the failure with react-hook-form and Froala present, then compare it with Froala removed and with appendTo set to "self". Trace Calendar's popup focus handling alongside the global keydown interaction; done means TAB moves focus from the Calendar input into the popup without requiring appendTo="self".
