Steps to reproduce:
1. Start Chromium with new (temporary) profile
2. Go to chrome://settings/advanced
3. Set Page zoom to 500%
4. For any page with content, open the Elements panel
5. Try to expand/shrink elements

What happens:
With the expanding/shrinking arrowheads zoomed 500%, but with code still at default zoom, it’s extremely difficult to hit the arrowhead in the right spot to expand/shrink elements. Depending on the selected Page zoom level the actual hotspot may even fall completely outside the arrowhead graphic (to the left from it).

What I expect to happen:
For the arrowheads and the code to both follow the Page zoom setting or ignore it, and either way, for the arrowhead graphic to function as the actual hotspot for expanding/shrinking elements.
