option compile from addKeyword doesn't change on a remove and then add again

[rgpro007]

Here my issue (if it's one):

I setup a keyword with addKeyword and the compile option. I have some external variables used inside. At the first iteration everything is ok, but at the second one we see the variables doesn't change. Is it a normal behavior or an issue ?

What version of Ajv are you using?

version 8.12.0

Your code

const AjvModule = require('ajv');
const ajv = new AjvModule();

const keyword = "variableKeywork";
const schema = {
    "description": "test",
    "type": "object",
    "properties": {
        "item1": {
            "type": "string"
        }
    },
    "variableKeywork": true
};

test({
    item1: "test"
}, true);
console.log('-------------------------');

setTimeout(() => {
    test({
        item1: 1
    }, false);
}, 5000);

function test(desc, value) {
    const now = new Date();
    const time = now.getTime();
    console.log(`Current time: ${time}`);
    ajv.addKeyword({
        keyword: keyword,
        modifying: true,
        compile: (value) => function validate(data, root) {
            console.log(`Time inside addKeyword: ${time} and value = ${value}`);
            return true
        }
    });
    console.log(`keyword present : ${JSON.stringify(ajv.getKeyword(keyword))}`);
    const validate = ajv.compile(schema);
    const isDataValid = validate(desc);
    ajv.removeKeyword(keyword);
    console.log(`data valid: ${isDataValid}`)
    console.log(`keyword present: ${JSON.stringify(ajv.getKeyword(keyword))}`);
}

Output obtained

Current time: 1716967536094
keyword present : {"keyword":"variableKeywork","modifying":true,"type":[],"schemaType":[]}
Time inside addKeyword: 1716967536094 and value = true
data valid: true
keyword present: false
-------------------------
Current time: 1716967541145
keyword present : {"keyword":"variableKeywork","modifying":true,"type":[],"schemaType":[]}
Time inside addKeyword: 1716967536094 and value = true
data valid: false
keyword present: false

What results did you expect?

the ajv.removeKeyword really remove the keyword and allow us the define it again.

Are you going to resolve the issue?

Can you please produce a minimal example using this runkit template? It should be possible to reproduce the issue without express.

Hello,
I have updated the example with a runkit template : runkit example

I have looked into this and I have been able to replicate with an even simpler example.
