A very strange bug with SVG on iphone 4. Maybe someone came across?

Question

iPhone

Looking for a bug!
Dead or Alive.
Accused: when adding svg icons to the site, the layout floats, namely, there are huge indents from the icons themselves and a lot of scrolling in the parent block. There is no photo of the perpetrator.
Distinguishing features:
1. Appears only when adding svg code directly to html. When connecting the same icons through the img tag, it does not manifest itself.
2. Noticed ONLY on one device (iphone 4, ios 7.1) in chrome and safari browsers. On iphone 5 and a couple of androids, the bug did not show itself.
3. The bootstrap grid is used.
4. Disabling all plugins did not help, it's in SVG.
