Fields become disabled after re-creation

[SonyStone]

Description
If the FormlyFieldConfig is used for the second time and the first field is disabled, then other fields are also disabled.

It's hard to explain. If you click the toggle button several times in the example, you can see that the second and third fields are also disabled, when they shouldn't.

I'm not sure, but looks like it's related with #2598

I've reverted the commit that caused the issue, fixed in v5.10.9.
