Missing feature flags in client side SDK

Describe the bug When using the javascript SDK, most feature flags are never loaded. When I use chrome dev tools to inspect the request to https://app.launchdarkly.com/sdk/evalx/<key>/users/<token>, I only see 5 flags returned, despite our project having 41 flags. When calling client.variation(...) or client.variationDetail(...), it works for the ones that are returned in the request, but it does not work for all the other ones. Here is an example of what I get when I call client.variationDetail with one of the flags that are not present in the initial request:

{
    "value": false,
    "variationIndex": null,
    "reason": {
        "kind": "ERROR",
        "errorKind": "FLAG_NOT_FOUND"
    }
}

To reproduce Here is the code I used to initialize the client:

const ldUser: ld.LDUser = {
    key: userInfo.username,
    firstName: userInfo.firstName,
    lastName: userInfo.lastName,
    email: userInfo.email,
    custom: {
        is_staff: userInfo.isStaff,
        client_name: clientInfo.name,
    },
};
const client = ld.initialize(CLIENT_SIDE_ID, ldUser);
client.on("ready", () => {
    console.log("ALL FLAGS: ", client.allFlags());
});

In the console message from the console.log("ALL FLAGS: ", client.allFlags()) statement I only see the same five flags that I saw in the response from the request to https://app.launchdarkly.com/sdk/evalx/<key>/users/<token>.

Expected behavior Would expect all flags to work.
