[Bug] New Tab block forces HTTPS protocol when using variables {{}} in URL input

[Mason-Ma-11417066]

Describe the bug
In the "New Tab" block, the URL input field automatically forces the protocol to https:// when the user enters the variable delimiter {{. It is impossible to keep or switch back to http:// once a variable is being used in the input box.
To Reproduce

Steps to reproduce the behavior:
1、Add a New Tab block to the workflow.
2、Double-click the block to open the settings.
3、Select HTTP as the protocol in the dropdown.
4、Start typing in the URL input field and enter {{.
5、Observe that the protocol dropdown immediately switches from HTTP to HTTPS, and a https:// prefix is automatically added before the {{.

Expected behavior
Entering a variable or specific characters in the URL input field should not interfere with or override the manually selected protocol (HTTP/HTTPS). The user should be able to use variables with the HTTP protocol.

Ran into the same problem. I added a RegEX block in front to filter it, and it worked, but it doesn't feel as convenient as before.
