Popup "wrong passphrase" appears even for correct passphrase

Preconditions

• HeidiSQL version:12.5.0.6677
• Database type and version:Percona XtraDB Cluster 5.7.31-34-57-log
• OS:win10 64bit

Describe the bug

When connecting to a database through SSH with passphrase authentication and providing the correct passphrase, a popup appears saying "wrong passphrase", yet I'm logged in to the database.

To Reproduce

1. create/save DB connection with SSH tunnel (MariaDB/Mysql) and using plink.exe / SSH tunnel with a private key file that requires a passphrase (ed25519)
2. connect
3. click OK on the "wrong passphrase" popup

Expected result: no "wrong passphrase" popup OR if the passphrase was indeed wrong, no connection to the server/DB
Actual result: "wrong passphrase" popup appears even when the correct passphrase is provided

Will have to test this myself, with a passphrased key.

I suspect my code for reading the plink output is again buggy.

Also have this problem, I have found one with symbols causing the problem: £(alt+0163)

@batteryf1 or @bst-biwac or someone: could you please test with the next build (6831).
I believe the shown "wrong passphrase" dialog is just shown in the wrong order, which should be fixed now. I could not reproduce that here, and probably the older plink executable caused a part of the issue as well.

Note that using a key with a passphrase will only prompt you when using plink, not ssh.exe. So prefer plink at the moment.
