File upload chooser prompt not working on any website

DoctorG

@vishv Tested now on Ubuntu 23 with multiple workspaces; file dialog appears for me.
Ubuntu 23.10 / GNOME 45.2 / Wayland / Kernel 6.5.0.14

//EDIT: ~~Perhaps i will try to install a Manjaro on my VM to test in the next hours.~~ Sad, Manjaro crashes on Virtualbox, i can not test and invest more time.

Copying the example in case if link will broke

function readSingleFile(e) {
  var file = e.target.files[0];
  if (!file) {
    return;
  }
  var reader = new FileReader();
  reader.onload = function(e) {
    var contents = e.target.result;
    displayContents(contents);
  };
  reader.readAsText(file);
}

function displayContents(contents) {
  var element = document.getElementById('file-content');
  element.textContent = contents;
}

document.getElementById('file-input')
  .addEventListener('change', readSingleFile, false);

<input type="file" id="file-input" />
<h3>Contents of the file:</h3>
<pre id="file-content"></pre>
