I think it should have been fixed in 33badfd.
Sorry for the noise.

Title:
vnc websocket compatibility issue
Status in QEMU:
Invalid
Bug description:
WebSocket support in VNC should allow access from VNC client through
upgraded WebSocket connection. This feature is not working in IE
11/Edge with noVNC HTML5 client, in contrast to that in
Firefox/Safari, etc.
The reason that IE 11/Edge fails to accept the connection upgrade is
that the value equality of the `Upgrade` header field is checked in a
strict case-sensitive manner in QEMU side, however, the IE/Edge does
not send the exactly same string value `websocket` but a capital
letter `W` instead.
Defined in section 4.2.1 of rfc6455, the upgrade header field shall be
treated case-insensitively.
A patch shall be made in `io/channel-websock.c`, converting the value
of upgrade string to lowercase before comparison is made with
QIO_CHANNEL_WEBSOCK_UPGRADE_WEBSOCKET, to allow case-insensitive
comparison in the process.
