attempt to perform arithmetic on a secret value

[ljosberinn]

Describe the bug
When selecting an element added by LibEditMode, this error gets thrown:

3x ...Blizzard_EditMode/Shared/EditModeSystemTemplates.lua:180: attempt to perform arithmetic on a secret value
Stack:
[C]: in function 'secureexecuterange'
[Blizzard_EditMode/Shared/EditModeManager.lua]:695: in function 'ClearSelectedSystem'
[TargetedSpells/Libs/LibEditMode-13/LibEditMode.lua]:174: in function <...dOns/TargetedSpells/Libs/LibEditMode/LibEditMode.lua:166>

This is using v13, but I've formatted the library locally so the stack trace may be slightly off. L166 is onMouseDown

How to reproduce
Adding anything at all to the Edit Mode on 12.0.0 / Live throws the error.

What did you expect?
No error, assuming it goes away with 12.0.1 again anyway.

I assume you tried to change settings while in combat, which is not something LEM can do.

There aren't any workarounds/fixes for this other than letting two selections exist at the same time (really bad UX). Blizzard said they could possibly add something for this, but it won't be in until atleast 12.0.1 or later.

[ljosberinn]

Nope, not in combat, merely opening Edit Mode in a follower dungeons and clicked on the added frame.

This is on this version: https://github.com/ljosberinn/TargetedSpells/releases/tag/1.1.0

forgot to show bugsack so just for the record:

false positive caused by BetterCooldownManager presence, sorry

[p3lim]

Gonna keep it open because the underlying issue with combat still exists.
