UI becomes non-responsive after going to `/wallboard` while job is running

[stranger-danger-zamu]

First off, thanks for the helpful tool!

Description

Laminar's Web UI becomes unresponsive if there is a long running job and you try to access /wallboard without query parameters. I just typed it in manually instead of clicking the button in the UI and had the page hang.

Expectation

Redirecting the user to a default page (eg. /wallboard?filter=.*) instead of leaving the connection hang indefinitely until the browser culls the page.

Reproduction

Specifically, I was able to reproduce it by essentially creating a script that slept for 13 minutes and going to /wallboard without any query parameters.

Opening a new window or tab does not fix it. You can open a private/incognito window and accessing the site, but the original site will remain waiting for server.
