Highlight similar instances of a selected word fails when scrolling

I think I figured out the bug and how the problem is created and what I need to do to prevent it. It still exists and should be fixed in the software though.

For this example, I will pretend that the words that I am double clicking on and using the Find feature for are "TEST1", "TEST2", etc.

When I double left click on "TEST1", all the matching words in the file are highlighted, this is good and what should happen. Then I scroll and I can see all the highlighted "TEST1" words. If I then left click off of "TEST1", the words become not highlighted. This is expected as well.

Now, if I double left click on "TEST1" and then press ctrl+F (for a Find), the 'Find' box opens and "TEST1" is listed in the 'Find What' box and I can click the 'Find Next' box to go to each of the locations within the file that "TEST1" is found. This is expected as well.

Now at this point, I simply 'x' out or close the Find Box since I was done with searching for "TEST1". Now the "TEST1" word becomes not highlighted.

Here is the bug, If I then double left click on "TEST2", those words become highlighted, but when I go to scroll with the mouse, the highlighting of "TEST2" stops being highlighted and "TEST1" becomes highlighted instead.

 If I double left click again on the "TEST1" word and open the back up the 'Find' box and then delete the word "TEST1" from the 'Find What' box, and THEN close the 'Find' box, the functionality for double left clicking on a word and scrolling is restored.

Long story short, if you leave a word in the 'Find What' box when you 'x' out or close the 'Find' box, the software remembers that word and it messes up all subsequent left double click and highlighting of words until the 'Find' box is reopened, the word is deleted, and the 'Find' box closed.
