Webpage http://127.0.0.1:8111/import?url=.... download don't close

[FransS1945]

I'm submitting a (bug report)

Brief Description

After selecting a changeset in OSMCha and open it in JOSM, this empty webpage 127.0.01.... won't close,

What is the motivation / use case for this feature?

I often review mappings and use this option all the time. It becomes annoying to have to close the page every time.

What is the current behavior, (attach relevant screenshots) ?

Now I have to close this webpage manually

What is the expected behaviour ?

It should close after JOSM has been loaded with this changeset

When does this occur ?

All the time after opening a changeset in JOSM.

How do we replicate the issue ?

1 Open OSMcha in Firefox (any version) 2. 3. 4.
