Unable to copy URI in native browser share menu. Why?

Demonstration

When I utilise the share functionality:

web-share/index.html

08dadaa1f


      
          <p class="result"></p>
          
          <script>
            let shareData = {
              title: 'MDN',
              text: 'Learn web development on MDN!',
              url: 'https://developer.mozilla.org',
            };
          
            const btn = document.querySelector('button');
            const resultPara = document.querySelector('.result');
          
            btn.addEventListener('click', () => {
              if (!navigator.canShare) {
                resultPara.textContent = 'Web Share API not available';
                return;
              }
              if (!navigator.canShare(shareData)) {
                resultPara.textContent = 'Share data unsupported, disallowed, or invalid';
                return;

…at developer.apple.com/forums/thread/722185 (as an example) and choose to duplicate the URI into my clipboard:: ^[1]

…it’s unpastable:

Consequently, I am forced to utilise the QR code generation entry in its stead:

Solution

I don’t know whether to report this at

especially because the undermentioned appears to demonstrate that the modal window is ultimately spawned by #Plasma:

Which modal window?
You’ve linked to a bug report that has several images attached.

Does it also happen if you copy a link, e.g. from the URL bar, via keyboard shortcut or context menu?

Also: Firefox native or sandboxed (Flatpak, Snap)?

@krake, the one spawned by ECMAScript’s share() API:

It does not reproduce from the omnibox or <a href>s:

rpm -qa firefox returns firefox-136.0.1-1.fc41.x86_64. dnf5 info returns:

Name            : firefox
Epoch           : 0
Version         : 136.0.1
Release         : 1.fc41

Thanks for the info @rokejulianlockhart

I did some testing myself and can confirm with Firefox and Chrome natively.

Didn’t work at all with Ubuntu’s Chromium Snap, i.e. the menu does not even come up.

Which leads me to an educated guess that this might be functionality provided by the Plasma Browser Integration plugin/extension.

I think that either its browser side or host side (or library called by the host side) messes this up.

KDE bugzilla “product” is plasma-browser-integration

@krake, it must be, for mdn.github.io/dom-examples/web-share reports the undermentioned when it is disabled: ^[1]

Web Share API not available

Consequently, I’ve reported it at bugs.kde.org/show_bug.cgi?id=501811. Thanks!
