Modern UX Board Columns are misaligned

Products

• Clarity PPM On Premise
• Clarity PPM SaaS

Issue/Introduction

STEPS TO REPRODUCE: 

1. Login to the Modern UX
2. Go to the Common projects Module
   http://myserver/pm/#/projects/common
3. Go to the Project Board
4. Look to the columns alignmnent



Expected Results: The columns to be aligned
Actual results: The far right columns are misaligned

Environment

Clarity PPM 15.7.1

Cause

This is caused by DE53430

Resolution

This is fixed in 15.9.1

Additional Information

Note: if a large amount of columns are present on the board, the horizontal bar does not seem to be properly working at times

It seems that the columns that get misaligned are the ones that do not completely fit on the screen
If you are using a large screen and the columns fit, then there is no misalignment.
The page does not seem to be rendering correctly, if the whole page content does not fit on the screen

There is a corner case in 15.9 being investigated through DE58629:

1. Login to the Modern UX
2. Go to the Common projects Module
   http://myserver/pm/#/projects/common
3. Go to the Project Board
4. Open the Columns flyout
5. Exclude all of them
6. Include all of them

Expected Results: The columns to be aligned
Actual results: The far right columns are misaligned (pushed up) 

This latest scenario is fixed in 15.9.1
