Window loses focus on the initial 'Shift + Tab' press when the window is first opened

Pressing Shift+Tab initially when the Window is opened, moves the focus from the Window back to the Button that opens it.

Steps To Reproduce:

  1. Open REPL repro
  2. Click "Open Modal" Button
  3. Press "Shift+Tab"

Hi Alexander,

Thank you for sharing your workaround. This will be valuable for other developers encountering the same scenario.

For anybody also encountering this, here is our workaround:

 

   document.addEventListener("keydown", (event) => {
      if (!event.shiftKey || event.key !== "Tab") {
         return;
      }
      if (!(event.target instanceof HTMLElement)) {
         return;
      }
      if (!event.target.classList.contains("k-window")) {
         // only prevent "Shift+Tab" on the Telerik window itself
         return;
      }
      const modal = event.target.ariaModal === "true";
      if (modal) {
         // only prevent "Shift+Tab" on modal windows
         event.preventDefault();
      }
   });
