image in footer tag not lazy loaded

Hi,

I am using a HTML code in my footer which has a png image. I observed in Chrome Dev Tools that this image is not lazy loaded.

Is this supported? If not any plans to support this?

Below is the code for reference:

<form action="https://www.paypal.com/cgi-bin/webscr" method="post" target="_blank"><input name="cmd" type="hidden" value="_donations" />
<input name="business" type="hidden" value="XXXXXXXXXX" />
<input name="item_name" type="hidden" value="Fundraising" />
<input name="item_number" type="hidden" value="" />
<input name="currency_code" type="hidden" value="USD" />
<input id="xxxxxxxxxxxxxxxx" name="amount" type="hidden" value="" />
<input name="no_note" type="hidden" value="0" /><input name="no_shipping" type="hidden" value="1" />
<input name="notify_url" type="hidden" value="https://www.myheartontravel.com/XXXXXXXXXXXXXXXXX" />
<input name="lc" type="hidden" value="EN_US" />
<input name="bn" type="hidden" value="WPPlugin_SP" />
<input name="return" type="hidden" value="" />
<input name="cancel_return" type="hidden" value="" />
<input class="wpedon_paypalbuttonimage" style="border: none;" alt="Make your payments with PayPal. It is free, secure, effective." name="submit" src="https://www.myheartontravel.com/XXXXXXXXXXXXXXX/paypal-e1600551287963.png" type="image" width="150px" /></form>
