The path analysis of the website is divided into absolute path and relative path.
When there is a specified protocol, it is an absolute path: https://xxx or //xxx.
When using an absolute path, the protocol specified in the absolute path is used. When using relative paths use the protocol inherited from the parent.
So for your problem, you specified the protocol, which is an absolute path, so your problem will not occur. The idea is the same as above, you may redirect https to http.
