Unable to convert the layout block to inline block

[hieudole]

The shared layout blocks cannot be converted to inline blocks.
I found out that the block should have at least one property to be able to become an inline block, or if it has the attribute [InlineBlockEditSettings(ShowNameProperty = true)], it does not need to have any property itself.
However, the latest CMS 12.22.1 has a bug with the setting ShowNameProperty = true, so the inline block cannot be created. I have reported this bug to Optimizely.

Update: InlineBlockEditSettings was marked as obsoleted in CMS 12.22.2 and will be removed in CMS 13 according to this document https://docs.developers.optimizely.com/content-management-system/docs/inline-edit-settings
