Mines been doing it for years, especially when its dry. The only time it stands a chance of opening is when its wet.
I have to open as much as it will go about 1/2" and pull down. It tilts because the runners are spaced too far apart.
I think there is an adjustment on the upright runners, i had a brief look last year after removing door card and put it back together again.
Theres a membrane used for the side airbag. For it to work the inner door needs to be air tight. Disconnect battery, it could trigger airbags.
Dome out of line. You mean it tilts and locks up like mine, in effect wedging in.
For those with runners set properly some form of lubricant silicon, ptfe, furniture polish, etc.
