displayChar doesn't work when using pipe

[rdebeasi]

Describe the bug
When I use IMask.pipe, the displayChar feature doesn't seem to have any effect. The same configuration works as expected when using IMaskInput from react-imask.

Thank you!

To Reproduce

Expected behavior: Both inputs read XXX-XX-6789.

Environment:
