When using dashicons in sections the navigation bar height seems expands (see attachment). Is that normal?

(Did you try using the develop branch from github? There's a chance your issue has already been adressed there)
Latest from WordPress.org (2.3.6)
theme_mods
mytheme_Kirki::add_section( 'outlook_about_section', array(
'title' => esc_attr__( 'About', 'mytheme' ),
'priority' => 10,
'panel' => 'mytheme_front_page_panel',
'icon' => 'dashicons-align-left',
'capability' => 'edit_theme_options',
) );
Marked as a bug, will get it fixed and include in the next version.
Good catch!
Hi @aristath ,
I found another issue here that you may consider to look at it also. When adding a panel icon, sections (under this panel) are automatically adding that icon too. If I use different icons for sections under that panel then two icon displays in the sections. Let me give you the screenshots. Im not so good in english, still learning besides coding so please hang with me.
Panel Icon:
'icon' => 'dashicons-admin-home'
Section Icon:
'icon' => 'dashicons-menu'

Closing this one, will be fixed on #1125
