IDE crash when Deleting a control that is attached to a component that has a Property of that type of control using the IDE (OI)

• Lazarus/FPC Version: <Trunk__>
• Operating System: <Win10__>
• CPU / Bitness: <64/32__>

What happens

What did you expect

Steps to reproduce

<Drop A TcolorButton on the form drop a TColorDialog on the form Set the property of the TColorButton.ColorDialog to the TcolorDialog you just put on the form.

At this point all is well

Now delete the TColorDialog from the form.

The IDE will crash.

It appears the IDE or OI is refreshing before the property for the colorDialog get's set back to None.

That is just my thoughts on it.

Thank you and have a good day!
