jeanetienne Orion version is 1.3.19 (10) (WebKit 8615.8.1.10.1)
. (Running on iPadOS version 16.7.10 (20H350)
.) My only installed extension is TWP - Translate Web Pages; disabling it doesn't resolve the issue.
In terms of settings, it's been a while since I did settings-configuration in my Orion install, so I don't have much specific memory of what I set, but I at least don't remember changing anything which struck me as likely to cause problems here. (I'd likely have deliberately avoided it, since inability to reorder tabs has been pretty actively among my main impediments from using Orion as my day-to-day default browser on my tablet.)
