Scrollbars shifting position in editor when the line of code is larger that the editor window (4335667)

Scrollbars shifting position in editor when the line of code is larger that the editor window.
Steps to reproduce the issue:

Edit a package(or any pl/sl code) having navigator on LHS, editor RHS, standard desktop panels below. For example: My file is max 50 chars wide on the first 30 lines so I don't see a horizontal scrollbar when I open my file and am on line 1 - this is expected.

I scroll down the page by using my mouse to click the down arrow on the scrollbar.

When I scroll down to line 30, which happens to be more than 80 characters wide, the horizontal scrollbar appears, creating a second down arrow on the vertical scrollbar. The bottom arrow doesn't work, so I click on the arrow directly above which continues scrolling. First problem manifested.

Because Line 30 is the only line more than 80 characters, when I get to say line 55, and my visible lines are now all less than 80 characaters, the horizontal scrollbar disappears again which is expected, however, now when I continue clicking to scroll I end up clicking the space between the slider and the down arrow, causing my code to page down unexpectedly. Second problem manifested.
