Hi @Techn1x and thank you for reporting that!

Internal note:
This issue was introduced in the 9.2.0 by this PR: #15837

Workaround:
I prepared a small workaround that calculates the min width of the label- demo.

[Techn1x]

Thanks for the workaround! The other workaround is useHTML: true but only if the text being used is known safe, which may not be the case for everybody

A better workaround that calculates the exact width of the label- demo.
