Expected behaviour

When using a "remote" jupyter server, the "kernel picker" window allows you to choose among all the running sessions on the server to connect a notebook to. In the previous version of the Jupyter extension, the names of these kernels were shown, along with a clear indication of which was currently selected.

Actual behaviour

In the new version of the extension, the names are no longer shown, requiring a user to guess as to which session to (re)connect to. Moreover, the "currently selected" text showing which session is connected, is often almost or completely obscured. Both are illustrated below. (Only in the second screenshot can the "currently selected" text be seen at all, cut off as "Cu..." on the very right side of the top line...)

Also, the "last activity" text doesn't seem to update correctly; I just now re-ran a cell in the notebook, but the text remains unchanged for the currently connected session. (This also applies to the "0 existing connections" text; one might expect that the "currently selected" notebook would show up as having "1 existing connection", but no.)

This behavior pairs particularly badly with #7610, but even if that were fixed, what's the point of letting you choose among sessions if you have to guess which is which?
