It could very well be. I don't have a non-NS machine to test. The behavior
seems isolated to frames that have no-accept-focus set. It doesn't actually
require the frame to be a child frame. This is the minimal repro so far:
(progn
(let ((buffer (get-buffer " *foo*")))
(when (buffer-live-p buffer)
(kill-buffer buffer)))
(let ((buffer (get-buffer-create " *foo*"))
(after-make-frame-functions nil))
(with-current-buffer buffer
(goto-char (point-min))
(insert "1 This is a test\n2 This is a test\n3 This is a test")
(delete-region (point) (point-max))
(setq-local resize-mini-windows nil)
(setq-local mode-line-format nil)
(setq-local repro-frame
(make-frame
`(
(minibuffer . nil)
(no-accept-focus . t)
)
))
(let ((win (frame-root-window repro-frame)))
(set-window-parameter win 'mode-line-format nil)
(set-window-buffer win buffer)))))
It's easier to repro if after evaling you move the new frame so that it no
longer overlaps the original frame. Then click a few px from the bottom of
the frame--about half of a line-height from the bottom. You may need to
click a couple of times (slowly) around this area. I tend to have the best
luck towards the bottom left of the frame. Here's a gif:

One question is, on other platforms, if you inspect the start-event in
mouse-drag-region is it for the new frame or the original frame? For me on
macOS, it's for the new frame even though no-accept-focus is set.

Yes.
