Null target breaking fillable forms on different resolutions

When testing different dialog sizes, window sizes, resolutions, devices, sometimes the PDFViewer Form Fields throw an exception causing form fields to be unfillable. Listed below.

Empty


Which corresponds to 

this.onWindowTouchEnd = function(e) {
    t.signatureAdded = !1,
    t.pdfViewer.element.contains(e.target) ||
    t.contextMenuModule.contextMenuElement.contains(e.target) || 
    t.pdfViewer.textSelectionModule && !t.isTextSelectionDisabled && t.pdfViewer.textSelectionModule.clearTextSelection()
}

Tested with your PdfViewerServer Modal example:

<div id="target" style="width:800px;height:500px">
    <SfButton @onclick="OnClick">Open PDF Viewer</SfButton>
    <SfDialog @ref="@dialog" Target="#target" Width="50vw" Visible="false" IsModal="true" Header=
    "@Header" ShowCloseIcon="true">
    <DialogEvents OnOpen="OnOpen"></DialogEvents>
<SfPdfViewerServer @ref="@viewer"/>
</SfDialog>
</div>

This code will break the fillable element but if you change the SfDialog size to:

 <SfDialog @ref="@dialog" Target="#target" Width="70vw" Visible="false" IsModal="true" Header=

Then the fillable elements will work.


I'm not exactly sure what's happening here, but it seems to be when the container is below some certain size threshold, mainly discovered in partial window sizes and mobile device aspect ratios.
