Description
Describe the bug
I am using custom field meta's heavily, for example style={{ display: field.state.meta?.hidden ? 'none' : 'block' }}, for every field I have set of these meta's like dataSource, hidden, disabled, and others...
in example there is two field firstName and color, I have listener.onMount that hide firstName (through field.setMeta()) if color is "red", in v1.26.0 and before it works well, after this version it does not hide until I touch the field firstName
example use v1.26.0, change package version to see the problem
Your minimal, reproducible example
Steps to reproduce
- notice in example field
firstNameis hidden by default (it is hidden inonMount) - change the
colorto"green"fieldfirstNamewill appear - upgrade tanstack-form version to newer version
- after refresh you will notice
firstNamenow is not hidden - touch the field
firstNamenow it will hide
Expected behavior
compare by previous steps I exp expect:
- notice in example field
firstNameis hidden by default (it is hidden inonMount) - change the
colorto"green"fieldfirstNamewill appear - upgrade tanstack-form version to newer version
- field
firstNameshould still hidden by default

Research direction
Run the StackBlitz reproduction using the files named in package.json, src/simple-form.tsx, and src/App.tsx. Compare TanStack Form 1.26.0 with 1.27.7, following the onMount meta update and the firstName rendering behavior. Done means firstName is hidden initially and updates correctly when color changes without touching firstName.
