Hello,

Using the following svg image file

 -> https://commons.wikimedia.org/wiki/File:CaldwellStarChart.svg

when "emacs -Q" is toggled fullscreen on 1080p display and the above
file is opened, "C-x C-+" and "C-x C--" text-scale-adjust command won't
zoom to enlarge or shrink the rendered image.

The svg image is displayed at 50-percent the width of fullscreen.

If "emacs -Q" is opened and left at the default frame size and the svg
file is opened, the smaller displayed svg image (See A) will zoom to
enlarge once at 50-percent the width of screen after the frame is
toggled fullscreen (See B).

Expected behavior is zoom to enlarge/shrink happens in response to "C-x C-+" and "C-x C--".
