Go to symbol: Inconsistent logic when using wildcard prefix/suffix.

[5.1.1700]
I have the following 3 classes:
{code lang=java}

private class Foo {}
private class FooBar{}
private class BarFoo {}
{code}

Case 1: No wildcard - Showing with Foo as substring (as expected):


Case 2: Wildcard suffix - Showing Foo as prefix, but not "Foo" itself (expected also Foo to show here)

Case 3: Wildcard prefix - Showing same as Case1 (expected only symbols ending with Foo, i.e. Foo and BarFoo):


Bug or by design?
If by design, shouldn't case 3 only show "BarFoo" if matching the logic used in Case 2? (if wildcard means 1-n chars and not 0-n).

Thanks
