Description Lucas Koehler CLA 2019-02-07 06:13:43 EST 
The table renderer should use number aware sorting for String-based columns.
The multi reference renderer should use number aware sorting for the referenced objects' labels.
Number aware sorting means that integers inside a string are sorted like numbers instead of in lexicographical order. Example:
lexicographical order: a100 < a20 < a40
number aware sorting: a100 > a40 > a20

TEST INFORMATION
Summary of the critical part of the change
The sorting algorithm for multi references and text-based columns of tables and grids has been changed to be number aware. This means integers contained in strings are no longer sorted lexicographical but according to their integer value.
For instance:
Old sorting: 3a > 300a > 10a
New sorting: 300a > 10a > 3a

Potential regressions
Table or multi reference entries might sort in an unexpected fashion

Affected areas / use cases
Tables and multi references

Things that shall be tested
That the sorting works as intended respectively the new sorting is no problem for users.
