Description acc4commissions 2022-05-28 05:41:26 UTC 
SUMMARY
git 415b1a8 (it happened in git 0c31a5b too, and possibly in others as well.)

Copying/Cutting and Pasting gets really messy and behave unexpectedly when working with reference images. There are variety of symptoms(such as : not being able to copy the entire selection, sometimes the pasting being not working at all etc) but I can't reproduce everything all the time. 

One example tho :

STEPS TO REPRODUCE
1. Draw something in the canvas and import a reference image.
2. Copy or cut reference image
3. Select Freehand Selection Tool and select the drawing on the canvas. 
4. Try to copy paste it via shortcuts or whatever works.

OBSERVED RESULT
Krita paste reference images on the canvas, not the selected drawing.

EXPECTED RESULT
It should paste the drawing.

Regression occurred in https://invent.kde.org/graphics/krita/-/commit/7b62b5c4c16e5832c1c1b842d4bbc493098e0827.

When a reference image is present, it will always ask the current tool to handle the copy. In this case, the code will ask the current tool to handle it, which is a no-op in almost every case.

Grammar mishap... 

When a reference image is present, it will always ask the current tool to handle the copy. This will result in the KoToolBase no-op in almost every case.

Implement Reference Tool selection detection

While commit 6e8224c52025fa1bf8508c3d4a2f98ecd4964019 implemented the
correct logic, it is only valid if the current tool is the Reference
Image tool.

There's a method for just this purpose, KoToolBase::hasSelection(), but
the existing flow stems from SelectionHandler::hasSelection, which
operates only with shapes. So this commit implements the
corresponding override and changes the check to query the current tool
instead.
