In generated deployment script sp_refreshview is executed before creating index on an indexed view.

Context:
I have two databases (DB1 and DB2) with only one difference, Table_1 has different id type.
Each database has two identical views:
idx_view - indexed view that selects id and text from Table_1.
view_1 - regular view that selects * from idx_view WITH (NOEXPAND).
When I compare DB2 and DB1 and create a deployment script (with "Deploy all dependencies" option checked) using SQL Compare I get the following script:
------------------------------------------------------------------------------------------------------
SET NUMERIC_ROUNDABORT OFF
GO
SET ANSI_PADDING, ANSI_WARNINGS, CONCAT_NULL_YIELDS_NULL, ARITHABORT, QUOTED_IDENTIFIER, ANSI_NULLS ON
GO
PRINT N'Removing schema binding from [dbo].[idx_view]'
GO
ALTER VIEW [dbo].[idx_view]
AS
SELECT id, text
FROM dbo.Table_1;
GO
PRINT N'Dropping constraints from [dbo].[Table_1]'
GO
ALTER TABLE [dbo].[Table_1] DROP CONSTRAINT [PK__Table_1_id]
GO
PRINT N'Altering [dbo].[Table_1]'
GO
ALTER TABLE [dbo].[Table_1] ALTER COLUMN [id] [tinyint] NOT NULL
GO
PRINT N'Creating primary key [PK__Table_1_id] on [dbo].[Table_1]'
GO
ALTER TABLE [dbo].[Table_1] ADD CONSTRAINT [PK__Table_1_id] PRIMARY KEY CLUSTERED ([id])
GO
PRINT N'Refreshing [dbo].[view_1]'
GO
EXEC sp_refreshview N'[dbo].[view_1]'
GO
PRINT N'Altering [dbo].[idx_view]'
GO
ALTER VIEW [dbo].[idx_view]
WITH SCHEMABINDING
AS
SELECT id, text
FROM dbo.Table_1;
GO
PRINT N'Creating index [idx_idx_view] on [dbo].[idx_view]'
GO
CREATE UNIQUE CLUSTERED INDEX [idx_idx_view] ON [dbo].[idx_view] ([id])
GO
------------------------------------------------------------------------------------------------------
When i run the generated script on DB1 I get an error "Hint 'noexpand' on object 'idx_view' is invalid.".
This error is raised because
"EXEC sp_refreshview N'[dbo].[view_1]'"
is executed before creating the index on idx_view
"CREATE UNIQUE CLUSTERED INDEX [idx_idx_view] ON [dbo].[idx_view] ([id])".

Does anyone know why the deployment script is generated this way or how could I work around it?

    Hi @Ante_T thank you for your post. 

    Using your scripts, I've been able to reproduce the issue and I do see that the script is generated in the wrong order. So I will raise the issue with the Dev team and then get back to you with their feedback.

    Hi @Ante_T, just to let you know the Dev team have reproduced the issue as well (thank you for providing those reproduction steps!) They raised the issue on they github board and they will be updating me with their progress so I'll let you know as well.
