I managed to write some code that doesn't use a cursor, so hooray for performance 🙂
SELECT
ID = tmp.ID
,Value = t3.[Value]
FROM
(SELECT t1.[ID]
,MaxID = MAX(t2.ID)
FROM [dbo].[Test] t1
INNER JOIN [dbo].[Test] t2 ON [t1].[ID] >= [t2].[ID] AND t2.[Value] IS NOT NULL
GROUP BY t1.[ID]) tmp
INNER JOIN [dbo].[Test] t3 ON tmp.[MaxID] = t3.[ID]
