This topic is very important for a good mobile user experience.
If anybody is interested, I have a hard css fix for this:

.mobile-nav .wd-nav-opener {
position: absolute;
right: 20px;
height: 50px;
width: 100%;
background-color: transparent;
text-align: right;
justify-content: right;
}
.mobile-nav .wd-nav-opener.wd-active {
background-color: transparent;
color: var(–wd-primary-color);
}
