Cannot open WebDav folders with Thunar 4.16.11

[kitahei88]

Hello, all.
After upgrading Thunar to 4.16.11, I cannot open the WebDav folders that used to be available as "davs://myserver/folder".
I can mount the same WebDav folder with the mount command, so I think this is a problem with Thunar as a client, not a problem on the server side.
It may be for Thunar, not Gentoo.
Thunar stopped supporting WebDav since 4.16.11 ?
