Issue description

We use SPFx Form Customizer. There’s one detail I’m not entirely clear on—maybe someone can help me. The Form Customizer works as expected in normal Read/Edit mode on the current element. However, when I open an old version in the version history, I’d like to see that old version, not the latest version of the item. But I can’t find any information about the version (VersionNo) in the FormCustomizerContext:

With this additional information it would be easy to handle the rest, but it seems, this is not supported right now or am I missing something? Where could we ask to implement this additional property in a future SPFx Version?

Thank you.
