fix: Code suggestion gutter icons in Web IDE

Description

This MR contains two bug fixes

• It fixes the Code Suggestions gutter status icon (introduced in !1222 (merged)) in the Web IDE. The gutter icon doesn't load in the Web IDE because context.asAbsolutePath doesn't work in Web Extensions.

• It also makes sure that the gutter icon doesn't persist across tabs
