The previous commit put the channel-switching code in the wrong init block.
credits.js initializes two modals side by side — the points recharge dialog and
the withdrawal dialog — and the snippet landed in the recharge one, which has
no [data-jio-withdraw-method] element at all. Both symptoms followed from that:
methodField resolved to null so no change listener was ever bound, and the
initial sync never ran, leaving the note paragraph permanently hidden.
The block now lives inside initWithdraw(), and the stray copy is gone. The
behaviour itself was already correct — switching channels swaps the account
placeholder and shows or hides the channel note — it just never executed.
Verified in a headless browser against the real markup and stylesheet: the
placeholder starts as the first channel's hint and the note is hidden; switching
to the second channel swaps the placeholder and reveals the note as
display:block; switching back hides it again as display:none.
The contract test previously only checked that the code existed, which is why
it missed a placement bug that made the whole block dead. It now asserts
syncChannelHint appears exactly once, sits after initWithdraw(), and does not
run past the next function definition. 873 tests pass.
