How to store "okta-shared-transaction-storage" and "okta-original-uri-storage" in sessionStorage (as opposed to local)?

I have an Angular 15 application that uses the redirect auth flow. I setup a custom storage provider and while “cache-storage” and “token-storage” are showing up in sessionStorage correctly, “okta-shared-transaction-storage” and “okta-original-uri-storage” remains in localStorage. The docs do not reference either of these storage items at all–is there a way to move them off localStorage? Thank you.

const customSessionStorageProvider = {
	getItem: function (key) {
		return sessionStorage.getItem(key);
	},
	setItem: function (key, val) {
		sessionStorage.setItem(key, val);
	},
	removeItem: function (key) {
		sessionStorage.removeItem(key);
	}
}

const oktaAuth = new OktaAuth({
	issuer: 'https://${yourOktaDomain}/oauth2/default',
	clientId: '${yourClientID}',
	redirectUri: window.location.origin + '/login/callback',
	storageManager: {
		token: {
			storageProvider: customSessionStorageProvider
		},
		transaction: {
			storageProvider: customSessionStorageProvider
		},
		cache: {
			storageProvider: customSessionStorageProvider
		},
	}
});

var authClient = new OktaAuth(config);
