Elementchip error when using a converted donkeytail field

[jripmeester]

We've converted a site from Craft 4 to Craft 5 and when editing some entries with a donkeytail field the CP crashes.

TypeError: craft\helpers\Cp::elementChipHtml(): Argument #1 ($element) must be of type craft\base\ElementInterface, null given, called in
