Allow setting map height to percentage value (D8)

Just reporting on this... I recently updated to Drupal 10.3 and Leaflet 10.2.18 and my view maps were not showing. After some tinkering, I discovered the only way I could get them to show again was to:
1. Unset the height value in the view (leaving it blank)
2. Add the height CSS style to ".view-content>.leaflet-container" instead of just ".view-content"

E.g., in my case I changed this:

.view-map>.view-content {
	position: relative;
  height: calc(100vh - 200px);
}

To this:

.view-map>.view-content,
.view-map>.view-content>.leaflet-container {
	position: relative;
  height: calc(100vh - 200px);
}
