Wrong environment passed to node post when called by composite called by composite action

Describe the bug

The inputs from a composite action are used by a called node action in the post phase instead of the inputs passed to the called node action.

To Reproduce

1. workflow has a job with steps: https://github.com/check-spelling-sandbox/symmetrical-guide/blob/da624a50ec50529dfe6653d037b992fa07723b14/.github/workflows/test.yml#L9-L14

2. workflow has a step which calls an action: https://github.com/check-spelling-sandbox/symmetrical-guide/blob/da624a50ec50529dfe6653d037b992fa07723b14/.github/workflows/test.yml#L9-L11

3. which calls an action: https://github.com/check-spelling-sandbox/symmetrical-guide/blob/da624a50ec50529dfe6653d037b992fa07723b14/composite/action.yml#L18-L20

4. which has inputs: https://github.com/check-spelling-sandbox/symmetrical-guide/blob/da624a50ec50529dfe6653d037b992fa07723b14/call-node/action.yml#L1-L4

5. and calls an action: https://github.com/check-spelling-sandbox/symmetrical-guide/blob/da624a50ec50529dfe6653d037b992fa07723b14/call-node/action.yml#L8-L10

6. which has a required input: https://github.com/check-spelling-sandbox/symmetrical-guide/blob/da624a50ec50529dfe6653d037b992fa07723b14/node/action.yml#L2-L4

7. and has a main and a post: https://github.com/check-spelling-sandbox/symmetrical-guide/blob/da624a50ec50529dfe6653d037b992fa07723b14/node/action.yml#L7-L8

8. the main reports the input it was given: https://github.com/check-spelling-sandbox/symmetrical-guide/blob/da624a50ec50529dfe6653d037b992fa07723b14/node/main.js#L9

9. which logs that value: https://github.com/check-spelling-sandbox/symmetrical-guide/actions/runs/11422876413/job/31781374640#step:3:31

   node (main) 4

10. the post run dies: https://github.com/check-spelling-sandbox/symmetrical-guide/actions/runs/11422876413/job/31781374640#step:7:4

You can see a previous run where the code was slightly different https://github.com/check-spelling-sandbox/symmetrical-guide/actions/runs/11422865129/job/31781351496

Expected behavior
The input provided to the action should be present in the environment for the post action as well. And not the inputs provided to some other action (the caller of the action).

This is the reason I filed #3510

Start with the linked .github/workflows/test.yml and the composite/action.yml, call-node/action.yml, and node/action.yml reproduction files, then compare the inputs visible to node/main.js and node/main-post.js through the nested composite calls. Done means the post action receives the input passed to its own node action rather than the caller's input, without the reported required-input failure.
