SVG logo is not displayed in xwiki notifications emails

XWiki version : 10.11.9

I have an xwiki instance in which I modified the color theme and changed the logo ... the logo image is an SVG image. Here is the logo :
mylogo.svg

Note that, the logo is correctly displayed on the wiki header, see screenshot :

The issue is that the logo is not displayed in the notifications emails, the standard xwiki logo is displayed instead. See screenshot :

I did a test with another image format (jpg) and I did not reproduced the issue.
