Unwanted css after refreshing page

After integrating grapes to my platform a problem comes when, after refreshing the page, I click inside an elements : this one gets the style border: 3px solid rgb(0, 0, 0); This issue goes on with every type of element I've insert in the canvas and it shows only on the first element I click after refreshing the page.

There is a specific way to interact with the update element style event?
