<button type="button" class="rz-html-editor-button" @onclick=@OnExecute></button> 

HTML from 안에서 <button> 기본타입은 submit 임 ---> 따라서, 별도 폼안에서 button  사용할때는 type="button"

As per spec, <button> elements are by default of type="submit" when placed within a form. Set delete buttons to explicit type="button".

<form>
  type="button" @onclick="(() => ExecuteDelete(file.fileName))">x</button>
</form>
