Something similar is happening in filter fields on query grids.
<input data-bind="value: value" aria-label="<div style='text-align: left'>Title</div>" title="<div style='text-align: left'>Title</div>" data-role="autocomplete" data-text-field="Title" data-filter="startswith" data-delay="200" data-min-length="1000" data-value-primitive="true" type="text" class="k-input" autocomplete="off" role="textbox" aria-haspopup="true" aria-disabled="false" aria-readonly="false" aria-autocomplete="list" aria-owns="82aa3ad2-070d-499d-b66d-8d6bd8381dfd_listbox">
The "aria-label" and "title" attributes include HTML code.
