SUMMARY

When I press Ctrl-C while in Google Chrome's "omnibar" (URL bar), several (~4) context menus appear. I have to press Esc or click "Cancel" four times for the menu to go away. If I triple-click to select the entire URL, two context menus appear.

STEPS TO REPRODUCE
1. Go to a website in Google Chrome (does not work if not on a valid webpage).
2. Highlight the entire URL.
3. Press Ctrl-C OR triple-click to select all text.

OBSERVED RESULT

URL is copied to the clipboard AND two-four identical, stacked context menus appear.

EXPECTED RESULT

URL is copied to the clipboard and no context menus appear.


SOFTWARE/OS VERSIONS
- Linux Ubuntu 18.04
- KDE 5.12.7

ADDITIONAL INFORMATION

- This does not happen in Firefox.
- It only happens when the text in the "omnibar" is a valid URL.
- The context bar contains the following items:
   - The text "HTML document - Actions For: <url in omnibar>"
   - Several applications (e.g. Google Chrome, Firefox, etc.)
   - The text "Disable This Popup"
   - The text "Cancel"
