Why Leaflet map not loaded if the accordion is closed?

I use accordion from Vuetify and package nuxt-leaflet.

If when the page loads the accordion do not open immediately, the map will be like this:
Seen only part of, and navigation to other parts of the map, the layer will not boot normally.

If the page is loaded immediately open the step map, the map pokazyvaetsya fine:

Can someone explain why it enters the loading map? And how to fix it?
