ERC4626RouterBase.withdraw will approve an amount of vault tokens to the vault, but the amount represents the number of asset tokens taken out by vault.withdraw, not the required number of vault tokens, and since it normally requires less than 1 vault token to take out 1 asset token, it will prevent ERC4626RouterBase.withdraw from using all approved vault tokens.
and since safeApprove cannot approve a non-zero value to a non-zero value, the second call to ERC4626RouterBase.withdraw will fails in safeApprove.
