Inkscape randomly creating duplicate node after slightly adjusting node location

Summary:

Just randomly had a document where I tweaked the location of a node and it randomly duplicated itself for no reason.

Steps to reproduce:

  1. Open attached file: duplicate_node_issue.svg
  2. Go down to the tail of the 'R' and select the node at X: 251.285 Y: 5.260.
  3. Now, notice in the status bar, it will say that '1 of 42 nodes selected'.
  4. Now, go up to the Y coordinates box and type: 5.26
  5. Now, unselect the drawing.
  6. Reselect the drawing and look @ the node I pointed out in Step 2.

What happened?

Inkscape has duplicated the node at x251.285 y5.260, even though you have done nothing that should have warranted it to be duplicated.

What should have happened?

The node at x251.285 y5.260 should still be a single node, and not have 2 at the same exact location now.

On a side note, there's another way to duplicate this, and get a bonus duplicated node at the same time. Here are those steps:

  1. Open attached file. duplicate_node_issue.svg
  2. Select the drawing, and Copy it.
  3. Open a new document.
  4. Ctrl+Alt+V (Paste in place) in the new document. (This is so the coordinates don't change.)
  5. Zoom in on the 'R' on the new document.

What happened?
2 nodes have duplicated themselves. One at x251.285 y5.260 (same as above), and another one at (px) x216.930 y59.446 (bottom left part of the inner part of the R).

What should have happened?
No duplicated nodes after pasting the 'R' on the new document.
