devtools 'site cant be reached'

SUMMARY
***
Devtools does not open with F12 or right click + inspect.  Both give the generic Chrome 'site cant be reached' page.  When I run Falkon from the CLI this is the output that happens with the error.

js: Uncaught ReferenceError: Components is not defined
[15261:15261:0220/235200.401700:ERROR:CONSOLE(1)] "Uncaught ReferenceError: Components is not defined", source: chrome-error://chromewebdata/ (1)

***


STEPS TO REPRODUCE
1.  Open any web page
2.  Press F12

OBSERVED RESULT

Devtools pops up but with the Chrome error page:

This site can’t be reached
The webpage at devtools://devtools/bundled/inspector.html might be temporarily down or it may have moved permanently to a new web address.
ERR_FAILED

EXPECTED RESULT

Normal chrome devtools window.

Hello,

is package "qt5-qtwebengine-devtools" installed?

> Hello,

It was not.  When I install this it grabbed several other packages and everything works.  What seems odd to me is : 

1.  This happened on 2x different Fedora installs (Fedora XFCE and Fedora LXQT, different release versions).
2.  Very odd / unexpected that I install Falkon from Fedora repo and it *not* install qt5-qtwebengine-devtools which is clearly needed.
3.  In Fedora package qt5-qtwebengine-devtools should be marked as a dependency so Fedora will install it as well.

Perhaps none of these are the concern or responsibility of the Falkon team.

Thanks for your assistance it is very appreciated.

Yes, this is a responsibility of Fedora maintainers.

Also, the next Falkon version 24.02 is Qt6 only so you will need to install the devtools for Qt6 after you update (if nothing changes on Fedora aside).

Thank you for a confirmation of the proposed solution.

Best regards,
Juraj
