Style on SecretFormField

I’m trying to use SecretFormField, basically copying the configuration screen for the MSSQL and translating it into the newer SDK. I think this is right:

<div className="gf-form-inline">
    <div className="gf-form">
        <FormLabel className="width-9">Username</FormLabel>
        <Input className="width-10" placeholder=""/>
    </div>

    <div className="gf-form">
        <SecretFormField className="width-10" placeholder=""
                         isConfigured={this.configured}
                         onReset={this.reset}
                         inputWidth={9}/>
    </div>
</div>

but the formatting is not great. There main problem is that the ‘password’ box is not the same height as all the other controls (including the user input and its own form label) so it looks wacky.

Before I go monkeying with custom styles, is there something I’m missing on that would correct this?
