Tested this issue on latest chrome version 66.0.3350.0 with steps mentioned below:
1) Launched chrome reported version and navigated to URL: http://codelab.ktam.org/videord.html which has many videos
2) Played videos randomly
Observations: When played the video and selected the progress bar on more than half of it, for different videos observed different position of blue bar hilighting while video is playing.

@Dmitry Iljinskiy:
Please find the attached screen cast and provide your feedback on it, if possible could you please provide any test URL/file which help in verfying this fix.

Thanks!

The basic behaviour of the blue bar that it doesn't appear after the marker of current position (it's the essence of this bug). Because the blue bar shows what we have played. That is what I see in every sample of your screencast and it is OK.
Though at the first sample I noticed that the blue bar appeared a little before you clicked. Maybe it's not a correct behaviour and we have to create another issue (especially if this bug has stable steps to reproduce).
