[10.1.278 Pro] - Code folding issues

I've got some problems regarding code folding in SQL Editor.

I've even got an exception when trying to invoke the feature from the menu (Issue tracking number: 36652). I was experimenting with folding features on the following code:

Code:

SELECT
*
FROM
[dbo].[utvonal] AS u
;

SELECT
nsz.[id_nyomvonal]
,nsz.[datum_tol]
,nsz.[id_kocsiallas_a]
,nsz.[datum_tol_a]
,nsz.[id_kocsiallas_b]
,nsz.[datum_tol_b]
,nsz.[szakasz_sorrend]
,nsz.[tavolsag]
,nsz.[polyline]
,nsz.[id_szakasz_tipus]
,nsz.[ido]
,nsz.[id_szakasz]
,u.[GV] AS latitude
,u.[GH] AS longitude
,u.[szakasz_pont_sorrend]
#szakasz_pont
FROM
#nyomvonal_szakasz AS nsz
INNER JOIN
[dbo].[utvonal] AS u
ON u.[nyomvonal_id] = nsz.[id_nyomvonal]
AND nsz.szakasz_sorrend = u.[szakasz_sorrend]
)
ORDER BY
nsz.[id_nyomvonal]
,u.[szakasz_sorrend]
,u.[szakasz_pont_sorrend]
;

I've put the caret on the SELECT on the first line and selected Toggle Collapse from View menu. That triggered the exception. It is reproducible.

Also, most of the multikey hotkeys I've set up for folding functions are either not registered when pressed or their functions do not work:
Expand all blocks: Ctrl+K, F, U
Collapse all blocks: Ctrl+K, F, A
Toggle nearest block: Ctrl+= or Ctrl+K, K or Ctrl+Shift+o
Collapse all but current block: Ctrl+K, J

None of the chording hotkeys starting with Ctrl+K do register, the followup keys (F, K, J) simply type into the editor as if Ctrl+K wasn't pressed at all.

Funnily, Ctrl+Shift+L, which is also assigned to Collapse all but current block, seems to be working properly. It folds code without throwing the exception mentioned above.
