Metabox.io Custom Field Layout Broken

Metabox plugin edit custom field page breaks inside the uipress layout styling.
“mb-panel mb-panel--add components-panel” this element appears over the top of the main menu so you are unable to navigate ‘back’ from here.

Fix For Metabox.IO
styling needs to change .mb element (div #mb-app) to position relative (not fixed) and give a height (height 100vh).
div#mb-app {

position: relative;

height: 100vh;

overflow: hidden;

left: 0;

}

general extras that could help here and other plugins:
UIPress could do with ensuing menu is on top
“uixp-menu” uix left menu component could do with a zindex (even z-index of 1 would have kept visible at least in this situation)
div#uixp-menu {

z-index: 1;

}

ideally contents of “uix-right-column” should be restricted inside this area. but based on the issue may easier adding specific fixes like the one above for metabox.io….
