Realtime database `runTransaction` can't use async function as `transactionUpdate`

[Legend-Master]

[REQUIRED] Describe your environment

• Operating System version: Windows_NT x64 10.0.19045
• Browser version: Chrome 109.0.5414.75
• Firebase SDK version: 9.16.0
• Firebase Product: database (realtime database) (auth, database, storage, etc)

[REQUIRED] Describe the problem

Steps to reproduce:

Can't use async function in runTransaction, return value will be counted as null (remove everything from that path)

Relevant Code:

const result = await runTransaction(ref(db, 'test'), async (currentData) => {
	return 1
})

Hi @Legend-Master, thanks for reaching out. Currently, transaction handlers have to be synchronous which is why you are experiencing this behavior. I'll tag this as feature request but I can't give any estimation of timeline.

Ok, guess I'll wait
