Error displaying the edit form for original block once linked in Virtual Element

[jalamanderman]

Once an element that is inline editable is linked and used in a Virtual Element it is no longer able to be edited.

Steps to reproduce:

• Create a Content Block
• Create a Virtual Block and link the Content Block
• Click the content block and see 'Error displaying the edit form for this block

This only happens for inline editable elements.

Have reproduced a minimal, reproducible example using the silverstripe/installer boilerplate.

Problem from silverstripe> framework > Forms > Schema > FormSchema.php Line 118.

private function recursivelyValidateSchemaData()

Could not find a react component for field \PageElements_12_VirtualClones.
/vendor/silverstripe/framework/src/Forms/Schema/FormSchema.php:132

Can we add null check before check schemaType and component?
VirtualClone schemaType showing null exception.

When I place the following condtion, it is working.
if(!is_null($data[schemaType'])){

Thanks.
