Regression with decimal values and negative number in color gradient in the layer style panel #65566

What is the bug or the crash?

This is about the input fields related to the color gradient of a raster style when using the Layer Style panel:

When editing the two fields the decimal point is removed immediately after inputting it. It doesn't matter if I insert a . or a ,. I cannot add a - to create a negative value.

The regression does NOT affect the fields when accessing them through Layer Properties/Symbology.

Steps to reproduce the issue

1. Add a raster to QGIS
2. Press F7 to open the layer style panel
3. Make sure the Render type is Singleband gray
4. Try to change either the Min or the Max field by entering a decimal value or a negative number
5. Verify that the ., , or - is immediately removed when inputting it
