Map stash, multiple rows, highlight, unwanted (not-initiated) scrolling

Hi!


I have many level-16 maps. More than 2 rows, so a scrollbar and scrolling is needed.
In the highlight box I type "rare", so rare maps are highlighted.
With the mouse cursor I click (select) map basetype.


Currently the "Lighthouse Map" icon is selected (yellow background).




I click on the "Malformation Map" icon.




Expected: the Malformation Maps are selected (get selection), and no scrolling occurs.
Happens: (maybe the Malformation Maps are selected, but) an (unwanted) scrolling
occurs, and "Crater Map" is scrolled into view. Under the cursor is the "Crater Map" icon. (And
Malformation Map is out of view, need to scroll to get in into view. (And I found that it was
selected. As I remember.)) The Crater Map is 2 rows up relative to the Malformation.




If someone needs a bug ID, here is one:




After a number of clickings, the error does not (or does not necessarily) reproduces..
Maybe and exploration of rare maps happens.
Maybe after full exploration (of a tier), the error does not occur.
