Why does the "rel" attribute of the "link" tag have different values ​​in different situations (stylesheet or preload)?

Question

HTML

Good afternoon
Our site on bitrix https://www.decorbazar.ru/ does not pick up .css styles in Mozilla Firefox and Internet Explorer browsers, as it turned out due to the “preload” value of the “rel” attribute of the “link” tag.


Usually we carry out technical work on a copy of the site deployed on the local “Open Server”, deploying the site and opening it in the browser, I saw that the “link” tags instead of the value “preload” have the values ​​“stylesheet”, and the site deployed on the local is displayed with all styles.


Please tell me theoretically or physically it is possible that hosting somehow affects the link tag or maybe some other reasons? Thank you!

+ the onload event works in the code , which changes the value from preload to style. This is a hack that doesn't work well.
