`Tooltip.header_format` validation not consistent with `Tooltip.footer_format` #193

Closed hcpchris closed 2 months ago

The setter for Tooltip.header_format does not apply the same validation as Tooltip.footer_format. In particular, it does not accept an empty string as a value, instead coercing it to None which is not correct (raised in #183 ).
