#1899 rectangular select changes when saving a file

[b2f9h203]

I'm using

SciTE
Version 3.7.0 compiled for GTK+ 3.22.2
Debian sid

Steps to reproduce:
1. Use rectangular select e.g. select with alt+shift+mouse (at least in my configuration) or alt+shift+arrow keys
2. Press Escape (now only one cursor should remain)
3. [optional] (if rectangular select actually selects characters and is not just effectively a multi cursor, then deleting something in this step makes the bug disappear!) Try pressing del, only one character for the one remaining cursor will be deleted
4. press Ctrl+S (at least for me) which saves the file

After step 4 the prior rectangular selection suddenly is back, pressing now would now remove multiple characters.

What should happen:
cursors should remain unchanged by "save file"

I don't have a Debian setup but I can't reproduce this with SciTE 3.7.0 (or current 3.7.2+) on any installation I have including Fedora 25 with GTK+ 3.22.5.

There are various problems with GTK+ 3.22 which have been addressed in the repository with several changes including [4fcd47] but these have not yet made it into a release.

Its possible this is the virtual space issue mentioned in [#1992] which was fixed in 4.0.3.
