Why the columns of the board are not displayed in the same row?

Question

Until yesterday I saw all the columns of my board in the same row but as of today I don't. It only changes if I change Chrome's zoom to 90%.

I don't know why but it is already solved and I see all columns in the same row.

I'm seeing this issue too :(  . It makes the kanban board hard to comprehend.

Previously, as our board had more columns than would fit in a page width, there was the possibility to horizontally scroll in order to see all columns. It seems that now, the columns are 'wrapping'. Am not usually a fan of horizontal scroll, but for many columned data, its ok.
