It appears that Kate doesn't account for code folding when searching in vi-mode.

Testcase:

create a document with a foldable section. Inside of that foldable section, put a unique string. Place another copy of the same unique string before the foldable code. Put a few more lines then in the foldable section after the foldable section.

Fold the foldable code section.

Place your cursor before the first copy of the unique string.

Press '/' and type the unique string followed by a newline.

(You should have jumped to the first (non-folded) instance of the string while you were typing the unique string into the search bar, and should still be on it after pressing enter.)

Press 'n' to go to the next result.

You should jump to after the foldable section. I notice that the number of lines past the foldable section you jump is equal to the number of lines (starting from the start of the foldable section) into the foldable section the result is.

Bug 282323 might be the same thing, but I can't seem to figure out how to change the status (maybe I don't have permission?)

This is on Ubuntu 16.04 Trusty using the Ubuntu packages.
