According to the comment in the upstream code this is not what is
expected to happen.
Basically the previews mode is only meant to ALWAYS show the previews
when multiple windows are available, without focusing one first. While
if one window is there, there's no need for the preview.
The behavior you want can be easy achivied by patching the code with:
diff --git a/appIcons.js b/appIcons.js
index d5bcbf2..3cbbd6c 100644
--- a/appIcons.js
+++ b/appIcons.js

if (!Main.overview.visible) {
// If only one windows is present just switch to it, but
only when trigggered with the

- if (singleOrUrgentWindows && !modifiers && button == 1) {
+ if (hasUrgentWindows && !modifiers && button == 1) {
let w = windows[0];
Main.activateWindow(w);
} else
However I'm not sure it should be the default, while you can open a bug
upstream or request for a further mode that always shows the previews.

Dock click action "previews" focuses instead

With the Ubuntu dock click-action set to previews, focusing on one
program then clicking on the icon of a different program with multiple
windows focuses the most recently used window from that program
instead of showing the previews.
Steps to reproduce:-
1) Open multiple Terminal windows (or any program I guess, but I used
Terminal and Firefox for testing)
2) Open Firefox
3) Click on the Terminal icon in the dock
Expected behaviour:
Previews for all the Terminal windows are shown
Actual behaviour:
The most recent Terminal window is focused.
Additional info:
Appears to be a regression of #1947445, which was supposedly fixed in
version 70 but I'm on version 72. I've tried setting the click-action
via gsettings and by editing /usr/share/glib-2.0/schemas/10_ubuntu-
dock.gschema.override (as per #1770405) but neither has any effect.
