focused pointer surface can only happen when no button is pressed. But<br />
there are more conditions where we try to update the focused pointer even<br />
if a button is pressed. E.g. if the stacking order changes.</p>
<p>This happens when trying to move one of Qt's dock widgets:</p>
<ol class="remarkup-list">
<li class="remarkup-list-item">Press inside a dock widget</li>
<li class="remarkup-list-item">Qt opens another window, which is underneath the cursor</li>
<li class="remarkup-list-item">KWin sends pointer leave to parent window</li>
<li class="remarkup-list-item">dock widget movement breaks</li>
</ol>
<p>This change ensures that also this sequence works as expected and the<br />
pointer gets only updated when there are no buttons pressed, no matter<br />
from where we go into the update code path.</p>
