Now that the T8i is out on the shelves, the write-up says that.

"Contrast AF is used for 4K UHD movies"

I'm assuming that this camera does not have duel pixel auto focus in 4K.

Does this mean that the camera will not maintain continuous autofocus when shooting 4K?

I guess I found my answer.

Canon's EOS Rebel T8i reaffirms its commitment to DSLRs

"On the video side, it can handle 4K video at up to 24p, but only using the contrast detect autofocus. If you want Dual Pixel phase-detect AF for video, you'll be limited to 1080p shooting at up to 60 fps."

It's a limitation of the 24MP sensor, sadly. The M50, M200, and SL3 all have the same limitation. Only the new 32MP sensor in the 90D and M6II has fast enough readout to allow DPAF in 4K. It's very disappointing that Canon didn't use the new sensor in the T8i.
