`on-runtime-upgrade` does not run neither `pre_upgrade` nor `post_upgrade` without `--disable-mbm-checks`

Neither of the following examples runs those hooks:
--checks=pre-and-post

try-runtime --runtime ./target/release/wbuild/bridge-hub-westend-runtime/bridge_hub_westend_runtime.compact.compressed.wasm on-runtime-upgrade --disable-spec-version-check --checks=pre-and-post --blocktime 6000 live --uri wss://westend-bridge-hub-rpc.polkadot.io

nor --checks=all

try-runtime --runtime ./target/release/wbuild/bridge-hub-westend-runtime/bridge_hub_westend_runtime.compact.compressed.wasm on-runtime-upgrade --disable-spec-version-check --checks=all --blocktime 6000 live --uri wss://westend-bridge-hub-rpc.polkadot.io

The pre_upgrade nor post_upgrade hooks are only triggered when I add --disable-mbm-checks. It could mean that for MBM migrations we don't check pre_upgrade / post_upgrade - maybe intentional?

But the consequence is that e.g. for polkadot-fellows we just run pre_upgrade / post_upgrade only for Encointer see: https://github.com/polkadot-fellows/runtimes/blob/main/.github/workflows/runtimes-matrix.json#L104.

I think it could be related to the https://github.com/paritytech/try-runtime-cli/blob/main/core/src/commands/on_runtime_upgrade/mod.rs#L135-L139

        let sync_checks = if command.disable_mbm_checks {
            command.checks
        } else {
            UpgradeCheckSelect::None
        };

Start in core/src/commands/on_runtime_upgrade/mod.rs around the sync_checks assignment, then trace how --checks=pre-and-post and --checks=all are handled with and without --disable-mbm-checks. Reproduce the two commands against the provided runtime and live URI; done means the expected pre_upgrade and post_upgrade behavior is established and verified for MBM checks.
