Paginated Report in PBI Service - Column Header Rendering Issue

Update as of 10/08/2021:

It seems that an update to Power BI has resolved the example I provided, though I am still experiencing an issue with the following layout when rendering in the Power BI Service:

It's important to note that the "gap" between the Current Month and Prior Month sections is actually just a blank column - both sections are part of the same tablix. I've also edited the photo a little bit to include dummy values.

Still, though, the column headers are clearly being displaced and the third column header in each section is being squished (I've disabled the height growth on those cells, otherwise the third header takes up a large portion of the screen) or not even included on the screen as it gets "pushed out" so to speak.

Again, testing locally in Microsoft Report Builder, the layout is perfectly fine.
