Page layout may be unexpected due to Quirks Mode
It looks like you're getting a warning message from the Ruxit agent.
which is a monitoring tool used by Dynatrace.
The message is indicating that the unload event listener is deprecated and will be removed.
This is likely due to a change in the browser's behaviour or a deprecation of the unload event
in modern browsers.
The unload event is fired when the user navigates away from a page, closes the browser window,
or reloads the page.
However, this event is not always reliable, as some browsers may not fire it consistently.
To mitigate this issue, you can consider using alternative approaches to handle page unload events.
such as:
Using the beforeunload event instead, which is fired before the page is unloaded,.
Using a timer to detect when the page is being navigated away from.
Implementing a solution that doesn't rely on the unload event at all.
Regarding the "Page layout may be unexpected due to Quirks Mode" message,
It's likely related to the browser's rendering mode being set to Quirks Mode.
Quirks Mode is an older rendering mode that simulates the behaviour of older browsers.
but it can cause layout issues and compatibility problems.
To resolve this issue, you can try updating your HTML document type declaration
to use a more modern rendering mode,
such as <html xmlns="
http://www.w3.org/1999/xhtml"> or <html lang="en">.
This should help the browser render your page correctly and avoid Quirks Mode.
