I am using the bulletproof background tool found here to create background images that will work in outlook. Once this is done, I go to edit my newsletter template and paste the generated snippet into the code view and save then preview. It works splendidly.
However, going back into the template for further edits I have to keep re-pasting this code as magento annoyingly keeps removing the background attribute from the td and table. Very unusual, would anyone have an idea as to why this is occuring?
Snippet is:
`<table background="http://via.placeholder.com/1280x400" bgcolor="#FFFFFF" border="0" cellpadding="0" cellspacing="0" class="one-column" style="border-spacing: 0px; border-left: 1px solid #447282; border-right: 1px solid #447282; border-bottom: 5px solid #447282; width: 100%; max-width: 100%;">
<tr>
<td background="http://via.placeholder.com/1280x400" bgcolor="#ebfaff" valign="top">
<!--[if gte mso 9]>
<v:rect xmlns:v="urn:schemas-microsoft-com:vml" fill="true" stroke="false" style="mso-width-percent:1000;">
<v:fill type="tile" src="http://via.placeholder.com/1280x400" color="#ebfaff" />
<v:textbox style="mso-fit-shape-to-text:true" inset="0,0,0,0">
<![endif]-->
<div class="herotext">
<p>Introducing Our New Product Range!</p>
</div>
<!--[if gte mso 9]>
</v:textbox>
</v:rect>
<![endif]-->
</td>
</tr>
</table>`
The code is not out of the ordinary and I cannot fathom as to why this is occurring. If anyone could help I would thoroughly appreciate this.
