Does not open World Clock when "Add world clocks..." clicked in date and time menu

In 18.04, when the "Add world clocks..." is clicked in the date and time menu, the Gnome Clocks program opens, but it opens the tab that was previously open in the clocks program, which may or may not be the "World" clock tab. For example, if the "Stopwatch" was used last, the "Stopwatch" will open.

I wouldn't say this is a major bug, but is a usability issue. It is an annoyance for me, and may be even more confusing for users who are new to Ubuntu or Gnome Clocks, and don't know why a Stopwatch would open when they wanted a World Clock. They may not be aware that they need to explicitly click the "World" tab to get the world clocks *after* they select the "Add world clock..." item in the menu bar.

If this is the not the right place to report usability issues, I'm happy to close this out and report it in a more appropriate forum - please let me know.
