[Vuejs]-Vuejs binding to img src only works on component rerender

Like I said in the comment on my post. Turns out I’m an idiot. When displaying the preview, I used this.person.personData.imagePreview . When a user fetches a project from the DB, I just did this.person.personData = response.data. That works fine, apart from the fact that I had a different name for imagePreview on my backend. So I manually set it on the same load method when fetching from the DB like: this.person.personData.imagePreview = this.loadedPersonData.file. For some reason, that screwed with the reactivity of Vue.
