Deletion of submodule directory doesn't show up (BB-9073)

In the following commit the submodule directory 'matlab/sglib' was deleted:

https://bitbucket.org/codecs/codecs-code/commits/c93be38cd8d3dd80ff9ec873ab84e7db7bd787df

Unfortunately this is not visible on the page, it simply says nothing about a change to 'matlab/sglib'. When I do a git diff between the commits I get

diff --git a/matlab/sglib b/matlab/sglib
new file mode 160000
index 0000000..180281d
--- /dev/null
+++ b/matlab/sglib
@@ -0,0 +1 @@
+Subproject commit 180281d5705a4d9b3717378851b6ec268b1b5336

and gitk shows

--------------------------------- matlab/sglib ---------------------------------
Submodule matlab/sglib 180281d...0000000 (submodule deleted)

It would be nice, if bitbucket showed something similar to alert the user that something has happened to the submodule.
