<h2 dir="auto">Expected Behavior</h2>

<p dir="auto">After resizing my window tooltips should be repositioned correctly to avoid unnecessary scrollbars.</p>
<h2 dir="auto">Current Behavior</h2>

<p dir="auto">When i resize a window to a certain point which has a tooltip at the edge then the tooltip is wrongly positioned after the resize which results in unnecessary scrollbars. After moving the mouse over the button which creates the tooltip a few times it gets into the correct position</p>

<li>Resize the whole window until unnecessary scrollbars appear</li>
<li>Simply hover over the button</li>
<li>After moving the mouse away and again over the button the tooltip moves</li>
<li>After doing that a few times it moves into the correct position it should have been in initially</li>
</ol>
<h2 dir="auto">Context</h2>

<p dir="auto"><code class="notranslate">TextField</code> with a <code class="notranslate">label</code> set to something and <code class="notranslate">type</code> set to date but with no initial value displays the label and <code class="notranslate">mm/dd/yyyy</code> on top of each other in the <code class="notranslate">TextField</code>.  Once you enter the field, the label moves up as superscript and the mm/dd/yyyy remains and is readable.</p>

</ul>
<h2 dir="auto">Expected Behavior</h2>
<p dir="auto">When the date picker has no value, if it is going to display the expected date format in the field, it should treat that as a value and move the label up to superscript.  Alternatively, don't display the date format unless the user enters the field and there is no value.</p>
<h2 dir="auto">Current Behavior</h2>
<p dir="auto">Currently the label and date format overwrite each other if there is no value for the TextField.</p>
