Recently, I encountered a peculiar issue on my website where a tab positioned fixed on the right-hand side disappears when the viewport width becomes less than X due to media queries. While this functions smoothly in most modern browsers starting from ie6, I faced a problem while testing it on a virtual machine used by my clients. Surprisingly, the media query doesn't seem to be supported and the tab remains visible.
Has anyone else experienced this issue before or have any insights on how to resolve it?
Thank you.
