Bug for welcome panel not hiding (Solution)

I notice in the logs “wslp variable not defined “
In wp.admin.ui.php around line 545
Just change:

wsl_admin_welcome_panel()

from

if( isset( $_REQUEST["wsldwp"] ) && (int) $_REQUEST["wsldwp"] )

to

if (!isset($wslp)) $wslp = 'networks';
	if( isset( $_REQUEST["wsldwp"] ) && (int) $_REQUEST["wsldwp"] && isset( $wslp )){

Git:

function wsl_admin_welcome_panel()
 {
-	if( isset( $_REQUEST["wsldwp"] ) && (int) $_REQUEST["wsldwp"] ){
+	if (!isset($wslp)) $wslp = 'networks';
+	if( isset( $_REQUEST["wsldwp"] ) && (int) $_REQUEST["wsldwp"] && isset( $wslp )){
 		$wsldwp = (int) $_REQUEST["wsldwp"];
