Changing the ImageContent value of an object from an Uri sourced content value to an Object sourced content value makes it unable to go back to Uri
Any object supporting ImageContent has the problem
Here are 2 examples :
1 :
Context : In my plugin, switching between tools also switch the mouse Icon when you hover the canvas. The brush tool uses an Editable Image / Object type content and the Color Picker and Bucket Fill tool are an URI content.
Here’s the code block switching them :
In the video you see me switch between the tools and when I go from brush back to an URI tool, it only works once then on the second time, the image is stuck to the brush’s content while having the right size
2 :
Context : The preview button sets the ImageContent value of the ImageLabel to a render of the canvas. Pressing cancel reverts it back to the ImageLabel’s original asset id, yet it doesn’t display
Here’s the code for the preview button :
(Where you can see me set the image content to an Editable Image / object value)
Here’s the code for the cancel button :
(Reverts back to the old id in the first few lines, and then DESTROYS the preview editable image after)
the ImageLabel is still stuck to the EditableImage value that has been replaced and destroyed 
This has been a problem ever since the addition of the Object type
