Bug when duplicating

[yakovetsrr]

Describe the bug
It's not clear how duplication works on the board when drawing. Logically, duplication should bifurcate one line or replace copy+paste with a single action, but in this case you need to select the area of duplication. Now that duplication is clamped, a huge number of lines are inexplicably duplicated on the board.

Steps to reproduce the behavior:
First scenario

1. Join the conference
2. Start drawing on the board
3. Hold Ctrl+D and continue drawing
4. As a result, the lines will be duplicated until the number of marks is exceeded.

Second scenario

1. Join the conference
2. Start drawing on the board
3. Hold Ctrl+D and continue drawing
4. Stop drawing, but don’t let go of Ctrl+D
5. As a result, the lines will be duplicated until the number of marks is exceeded.

Expected behavior
I expect that when duplicating 1 line will bifurcate and repeat the first line or duplicate the selected area

Actual behavior

This duplication bug with Ctrl+D while drawing lines in bbb 2.7.7 is due to how tldraw in version 1.0 handles it's events. It was fixed in tldraw 2.0 and pulled in bbb 3.0, where Ctrl+D only duplicates selected shapes, not lines in progress.
This avoids the unintended duplications when drawing lines while holding down the shortcut key.

Only 3 is not stable yet, so we are still on 2.7.7, and students who know about such a bug sometimes try to sabotage classes in this way when they give everyone the right to draw on the board.

Well, I wonder, will this be fixed in 2.7 or is it just time to wait and plan the transition to 3.0?

How can I apply this change before release? In 2.7.7

I assembled the package and installed it for production. For some reason he messed up the domain settings, but I set them again and corrected the websocket proxy settings. And everything works great.
There is really one drawback, although it is not clear whether this is a problem.
If you select an object and hold down Ctrl+D, it will be duplicated until it falls within the limit on the number of annotations.
