Annoing CPU percentage width change

After an update today (on my Ubuntu 16.04) I saw that after the indicator graphs there is a CPU percentage usage which (normaly) changes constantly and when it changes from one number percentage to two number percentage the width of the field changes and move all other icons (of the indicator and other programs) to left. When it gets back to one number percentage - the width gets smaller and all icons moves back.

Example:
one number percentage:
CPU 6%
one numbers percentage:
CPU 13%
The width of the second one is bigger.
I understand that when the percentage is less than 10 there will be unneaded space between "CPU" and the number of percentages, but this happens constantly so it's very annoing. This is why I'm reporting it as a bug. Please fix it.
You may set a hard width for the field (enough for two or three number percentage) and it will not change constantly.
