[error]  * static method apply(java.lang.String,scala.Function1)calico.html.EventProp in class calico.html.EventProp does not have a correspondent in current version
[error]    filter with: ProblemFilters.exclude[DirectMissingMethodProblem]("calico.html.EventProp.apply")

I think this is about a static forwarder to this:

object EventProp:
  @inline private[html] def apply[F[_], E](key: String, f: Any => E): EventProp[F, E] =
    new EventProp(key, _.map(f))

I would assume we don't care about Java calling us so it's safe. @armanbilge please take a look boss

While I agree it's safe, I have a couple concerns:

1. The filter is not specific to static forwarders (MiMa doesn't support this), so it could inadvertently filter an actual breaking change in the future.
2. I don't understand how your changes caused that to happen to begin with? 🤔

Bug maybe.

A workaround is to use @targetName annotation to call it something other than apply in the binary.

Makes sense. Added targetName, seems to work fine (locally) without the exclusion.
