Bug affecting Display Fonts

I’m not sure this plugin is still supported. I write on the assumption it may still be supported, although I note it’s not been updated for 10 months, and on the basis of that plus the bug I’m about to describe I’ve disabled it and replaced it with an alternative, which is a shame because i preferred the styling of the one I replaced. But the bug is that when the banner displays it often (most of the time) blocks the display of the chosen display fonts (leaving the default fonts showing instead). It also leaves the top margin shrunken after the banner has been closed. Both these faults are eradicated once the page is refreshed or on navigating to a new page, but it is slightly annoying nonetheless. This is on the Twenty Twelve Theme and the bug has persisted through versions 5.5 and 5.4 (I wasn’t using the plugin prior to that. If anyone is supporting this plugin still and can provide a fix, I’d appreciate it if they could reply here, as I’d quite like to re-install it if the bug can be fixed. Otherwise if anyone is looking for a replacement, the one I found that matches most closely and isn’t overly complicated in terms of options for cookie control, is the one on the free version of jet-pack.
