3.5.0 Beta
Please apply first PR #8638 to make it more obvious.
Test:
Go to components > Contacts
Click headline Language to order by language and at the same time have a look on filter field Sort Table By.
For a short moment "Language" appears instead of "Language ascending" or "L descending".
Then "Sort Table by"
After ordering is completed open dropdown "Sort Table by"
You'll see 3 options for Language in list."Language ascending", "Language descending", "Language" (at end of list).
