Rider split-mode API FrontendOtherwiseBackend

IntelliJ Platform
1

Hi Team

In Rider 2026.1 split-mode my diff-toolbar actions trigger repeating ‘DiffToolbar’
toolbar creates new components for 20 updates in a row warnings because Rider wraps backend-registered actions in BackendDelegatingAction on every update cycle.

The clean fix is the pattern JetBrains uses internally: ActionRemoteBehaviorSpecification.FrontendOtherwiseBackend + putClientProperty(SKIP_FALLBACK_UPDATE, true)

but both are @ApiStatus.Internal, so Plugin Verifier flags it.

Filed a feature request with the details: https://youtrack.jetbrains.com/issue/IJPL-242742 to request to change to experimental.

Thanks
