Email Signature Images Width and Height Lost

I run an email signature generator tool that helps people create email signatures. Our signatures have been working for Outlook Web for a very long time now. We have not changed anything about the formatting of email signatures recently.

Within the past 2 weeks some of our customers have been complaining that when pasting their email signature into Outlook for Web (as well as New Outlook for Windows) that the images within their email signatures get too large.

We store images at 2x size so that they look good on mobile and high DPI devices. This has worked for a very long time. The images then have a height and a width attribute (as well as styles) to tell them to render at the appropriate size.

Unfortunately I am not able to duplicate this issue myself using Outlook for Web and New Outlook for Windows. I have sat on 3 Zoom calls now with customers where they demonstrate the issue, and then I take the exact same signature and paste it on my side without issue.

Signature Logo Sent From Their Outlook Web Email:
<a href="https://company.com" target="_blank" style="display: block; height: 26px;"><img alt="Company logo" src="https://company.img.email/images/company.png"></a>

Signature Logo Sent From My Outlook Web Email:
<a href="https://company.com" target="_blank" style="display: block; margin-top: 0px; margin-bottom: 0px; height: 26px;"><img alt="Company logo" width="350" height="26" style="width: 350px; height: 26px; margin-top: 0px; margin-bottom: 0px; display: block;” src="https://company.img.email/images/company.png"></a>

As you can see the width, height, and styles have been removed from the image tag on their "version" of Outlook for Web, but not on mine.

I have had multiple people report this issue through the help menu within Outlook. This affects their jobs as well as our platform. I have tried other email signature generators and it is affecting them as well. Please fix it as soon as possible!
