Adding story formats repeatedly tries back URLs if you type in the field

The "Add story format" panel repeatable tries to resolve the URL after each character is entered into the field, so simply typing https://t or https://tw is enough to cause (an) instance(s) of the following error...

GET <url> net::ERR_NAME_NOT_RESOLVED

...and possible the following error as well...

Mixed Content: The page at '<URL>' was loaded over HTTPS, but requested an insecure script '<URL>'. This request has been blocked; the content must be served over HTTPS

,,,all depending on how slow you type or if you pause while typing.

If I tried to overcome the above issue by copy-n-pasting a valid domain like https://twine2.neocities.org/ into the field I get a Cross-Origin Read Blocking (CORB) blocked cross-origin warning before I can type the rest of the URL.

I would recommend not trying to resolve the URL until the end-user selects the "Add" button.

p3 because many users don't do this (based on my totally unscientific opinion) and I'd guess most are copy/pasting a URL rather than typing it in character by character.

2.5 partially fixes this behaviour, so it might be closable. The partial URLs are still tried, but the error no longer displays.
