BUG - unable to widen dropdown in third column of parameters pane in paginated reports

[wbmarshall_IMA]

I've encountered a strange bug with paginated reports in the parameter pane.  Initially reported by one of our users.  There are certain cases where the user is unable to widen a dropdown list in the parameters pane of a paginated report when using the control in the bottom right of the menu (as shown in red):

This only seems to apply in circumstances where there are three or more columns in the parameters pane.  Menus in the first two columns are never affected that I can tell.  Menus in the third column are affected unless there is a fourth column with a parameter that includes a box (it still fails to work if the fourth column only contains a radio button, for instance), or if the fourth column is not fully visible due to the width of the columns (however, if you scroll to make the fourth column visible then it starts working again).  Also, note that the bug only seems to affect the ability to make the selection list wider.  I am able to make the list taller in all of the cases I've tried.

I've done some searching but can't find anywhere that this bug has been previously reported.  Is this under consideration to be fixed?

This only seems to apply in the service.  I am unable to recreate this issue in Power BI Report Builder.  We don't host an on-prem PBIRS instance, so I am unable to confirm whether that is also affected.

Hi @wbmarshall_IMA ,

Is this happening on all your paginated reports?
I can't seem to reproduce this issue, what version of Power BI Service are you currently using?

Best regards.

@v-xiaoyan-msft most of our paginated reports do not make use of more than two columns in the parameters pane.  I have checked a few of the ones that do and they are all affected.

We are using service version 13.0.20866.74
