In low-version shell browsers and mobile browsers such as 360 Extreme Speed, the font in the tag in svg cannot be scaled correctly, but it is normal in the latest version of Chrome.

When the window is reduced, the font size in the speed browser will not be reduced when it is scaled to 12px. It works fine in the latest chrome. If you open the 360 Extreme Speed debugging tool and remove the display:block attribute, the scaling will be normal. But setting display:inline directly in css does not work either. it's wired.
