When exporting a report as a .pdf, the report tooltips do not show in the output.
Tooltip report page doesn't support in exported PDF currently. For your requirement, you can submit a idea here: https://ideas.powerbi.com/forums/265200-power-bi-ideas

I wasn't talking about tooltip report page, just standard tooltips.
Standard tooltip is not supported as well. The visual in exported PDF like a snapshot, we can't do any interactive action with it.
