No image on Philips TV when turning on while connected over HDMI/USB-C port replicator (`[drm] *ERROR* Link Training Unsuccessful`)

Connecting a USB Type-C port replicator [1] to the only USB Type-C port of the Dell XPS 13 9360 with Debian sid/unstable and Debian’s Linux kernel 6.10.5, and then connecting a Philips 40PFL5206H/12 TV device, that is powered off or in standby, to the HDMI port, and then turning on the TV, the monitor is detected but no image is shown.

(cf issue #9705 for EDID has corrupt header)

Plugging in the HDMI cable, while the TV is already running, an image is shown (as can be seen later in the logs).

This is always reproducible. Note, I am only going to have access to the TV tomorrow.
