Positioning of Page tabs in bottom toolbar wrong for large number of pages

I use CorelDRAW to create sets of icons for UI design. In each project's document, I will have many pages, one for each icon.

The more pages I add, the more the pages tabs in the bottom toolbar are mis-aligned. I believe if I reach 100 or so pages, the last page will be completely hidden to the right on the pages tabs toolbar (see attached screenshot). It seems this needs some adjustment to the algorithm to position the page tabs in this side scrolling toolbar.
