Calendar isn't an 'active' menu item

[humantex]

The calendar's link will not show up as an active/highlighted link in either a main or user created menu - or - the off-canvas menu for mobile. Whether I'm testing in Firefox Dev edition, or on an actual mobile phone or tablet, it still renders the same way.

The site I'm working on is using using a slightly modified Avanti theme, but no hover/active/focus parameters have been removed or disabled from CSS - just adjusted for colors.

• If I create a FormMaker page and use its embedding code within a standard page, I'll get an active menu item, on or off-canvas, when adding it as a page item.
• If I use a Gallery as a link item, I'll get an active menu for main and off-canvas menus.
• All standard pages show active in all menus, whether added as a page or a link.

There's nothing I'm aware of to try using the calendar with an inserted shortcode in a page, but as it is, there's no menu links showing when adding it as a linked item.

Well, I noticed something odd after going back to add more .pages. It looks like active child-items in the menu will cause the parent to call its CSS element as ':active". Now I'm wondering if there's something with either the theme - or uikit's - CSS that's affecting the behaviour, and it's not the calendar at all.

I do now, and will in the future - need to have a child menu item under the calendar as a parent, so I may have to dig a little deeper.

After a bit more time, it looks like - even with the parent/child behaviour - the calendar's menu entry still doesn't become an active element when it's own page (in my case, parent page) is displaying... so the same basic issue is still in play. This doesn't look like a css issue after all, unless I've missed something.

The site is now public and active. after moving it to it's parent domain... https://condoatsiestakey.com

With it no longer being either a subdomain or sub-folder, the menu issue is still present on the off-canvas panel.
