Leaflet always uses the full width

[amks1]

Description

I'm trying to fit leaflet into one third of the page width.

with ui.row().classes('w-full'):
    ui.label("Test1")
    ui.label("Test2")
    ui.leaflet()

Output:

If I do something like this, the map doesn't show at all.

with ui.row().classes('w-full'):
    ui.label("Test1")
    ui.label("Test2")
    with ui.element('div'):
        ui.leaflet()

Output:
