Fix bug UpdateComment, Fix styling on Comment

- There was a bug that updates to comments were not being displayed
because of a v-show... https://vuejs.org/v2/guide/conditional.html#v-if-vs-v-show
Basically, what it says that is important for this bug is
"v-if...ensures that event listeners and child components inside the
conditional block are properly destroyed and re-created during toggles"

- Since we are using the editor to display comments in ContentViewer, we
need to set the min-height to 0px
