The "i" modifier is translated into "(?i)" that does not corresponds with matchCase flag ("Case Sensitive" option in GUI) in the control plane. This may introduce a confusion when user writes a regex with "i" in advanced mode, and switch to simple mode. User would expect "Case Sensitive" option is unchecked to "i", but in GUI it displays as checked. The matching behavior is as configured with "i", case-insensitive.
Possible confusion in GUI.
In advanced mode, configure following pattern with "i" modifier. re2:"/abc/Vi"; norm;
Use "nocase" modifier instead.
None
