Additional relevant information (e.g. frequency, ...)

This issue occurs constantly in Firefox. It does not occur on other browsers.

[proxyconcept]

This page is rendering with XML data and XSL transformations (applied by the browser):

• a field contains an icon in SVG : it's composed of XML tags (like HTML)
• the XSL transformation use this data with an option "disable-output-escaping"
• but Firefox don't accept this option so the SVG is escaped and we see his code

Corresponding code:

• www/include/monitoring/status/ServicesHostGroups/xml/serviceGridByHGXML.php (lines 324 & 328 with the "returnSvg" function call)
• www/include/monitoring/status/ServicesHostGroups/xsl/serviceGridByHG.xsl (lines 90 & 94 with the "xsl:value-of" transformation)

Mozilla reference: https://bugzilla.mozilla.org/show_bug.cgi?id=98168

I think it's better to remove the SVG from the XML (just a text, or maybe a path to the icon).

[proxyconcept]

Maybe my PR is not the right way to resolve this, because a solution seems to already exists with a <span class="svgs">...</span> around the SVG code.

Then the right fix should be to continue this wrapping for all the SVG icons in the XSL files...

[proxyconcept]

Already fixed with #11659

[dsisysteme]

Thank you @proxyconcept for your answer. According to #11659 the patch is intended for 22.10.x version. We have now to wait for the release of this version.
