As soon as the user starts interacting with the content in the grid in MUX, such as opening a project grid and returning to the list view, or opening the "Detail" tab, the firsts two or three columns switch positions between the panes.
Steps to Reproduce:
Expected Results: The pinned column position should be honored while working on the view and state of the view is unsaved.
Actual Results: The issue occurs when certain columns in the list view are pinned to the left and the Details (or Columns) panel is opened, such that the combined width of the pinned columns and the Details panel exceeds the browser window width. This can also occur when the browser window is resized and the width of the pinned columns alone exceeds the available window width.
