Data loss when you start creating a host and accidentally click outside the pop-up window

Is your feature request related to a problem? Please describe.
I recently created a bunch of hosts in quick succession because I had to migrate some sites to a new Nginx Proxy Manager at work
While copying and pasting back and forth between two interfaces, I've accidentally clicked outside the pop-up window before when I was almost done creating it.
And clicking it closes the pop-up, which makes me lose the info I've already entered :(

Describe the solution you'd like
When you start entering information into any new creation pop-up and accidentally click somewhere else, causing it to close, the system should simply ask for confirmation to make sure that's what you intended
or, as with other tools, highlight the close button

Describe alternatives you've considered

Additional context

No files or tests are named. Start by locating the frontend components for host creation and other creation pop-ups, then inspect how clicking outside currently closes them. Done means entered data is not silently discarded and the intended confirmation or close-button behavior is consistent across the affected pop-ups.
