The little “X” is missing on the close document tab.
macOS 10.13.6, Safari 12.0.2, gravit designer 3.5.6 online version
To note: the “X” shows up when using the macOS desktop app 3.5.6
I just tried with MacOS 10.14.1 and couldn’t reproduce the issue. Maybe it’s related with the MacOS version.
Strange - works fine in current Chrome and Firefox (under macOS 10.13.6) , seems like it’s Safari specific. Oh well.
