PDM <= 1.0.2: VM Migration: Endless Line in Task Viewer

[beckerr]

I'm migrating a VM from one cluster to another.
In Task Viewer, the progress of the data transfer is displayed as a veeeery long line because line breaks aren't shown.

However, when I copy and paste this line from Task Viewer into a text editor, the line breaks are there.

Screenshot of Task Viewer:



Text after copy and paste to editor:

tunnel: accepted new connection on '/run/pve/188.storage'
tunnel: requesting WS ticket via tunnel
tunnel: established new WS for forwarding '/run/pve/188.storage'

the issue here is that the underlying tool (dd) prints '\r' as "newlines" (it's to overwrite the old text on the cli)
on the commandline, etc. it's possibly "normalized" to a \n but the web ui framework simply print it as is, and \r will not be interpreted by the browser ...

we could theoretically replace these in the frontend but then the paging virtual scrolling is not correct anymore. otherwise we could replace it in the backend, but this is probably very costly to do for all tasks (since we have to to id for the whole task...)

we could also fix it for the specific tool calling here, but this is probably not the only place where this happens...
