Toolbar disappears when panning the map on MacOS Safari
I use BRouter with my Mac Book and iPad. I have the problem that when moving the map, the left toolbar disappears again and again. it is covered by the map and rarely reappears. Unfortunately, you can't plan like that. On the Mac I can help myself by installing the Edge Browser, so I don't have this problem. Unfortunately, this doesn't work on the iPad.

I see that you're using bikerouter.de. Can you reproduce this issue on https://brouter.de/brouter-web/ as well? (Just to eliminate the possibility the error is specific for bikerouter.de)

yes with BRouter 0.17.0 and the new version 0.18.0 I also have these problems. It looks like it only occurs at a certain zoom level
I've also noticed this a few times in the past (on DuckDuckGo Browser & Safari on iOS, both iPhone and iPad). But never really had a look, since I (also) thought it was a problem with my instance only :)
Having dug into it a bit w/ current version on brouter.de/brouter-web/ instance ... this seems to be a z-index issue. If brouter-web is in that particular state and you select elements from the dev tool, it can be seen that it's indeed at the right place. Yet there are elements in .leaflet-tile-pane and .leaflet-marker-pane that have higher z-index's.
Adding a manual/explicit z-index: 99999 style to both .leaflet-control-container and all its children, immediately makes the elements re-appear.
Bug Report w/ Webkit: https://bugs.webkit.org/show_bug.cgi?id=238589 (there's a fix, but it seems not to be included in latest iOS)
Leaflet has it as well as mentions a work-around: https://github.com/Leaflet/Leaflet/issues/8068
