Describe the bug

Sometimes (very often) the first key pressed in the input field of the RadzenAIChat not detected. From the second keypress it works.

To Reproduce
Steps to reproduce the behavior:

  1. Put a RadzenAIChat component on a Blazor project (I used server side rendering)
  2. Implement an IAIChatService implementation, register, use.
  3. Try to use it for chat.
  4. It will occur.

Expected behavior
All keypresses are detected, and displayed/registered, even the first.

Screenshots
Impossible to prove it with screenshot.

Desktop (please complete the following information):

  • OS: Windows
  • Browser: Firefox, Chrome, Edge
  • Version: Latest.

Additional context
Maybe it is a shift related problem, people mostly start their sentences with capital letters.
