Macro: quick double paste operation from clipboard leads to invalid entities on canvas

[AlexeyGirin]

When user pastes structure to canvas twice with a short interval, this may lead to "broken" canvas with invalid entities (cannot be remove, survive canvas clearing, etc.). The problem easier reproduces on big inserted structures -- assumingley when you try to paste new structure before pasting of previous one is completed.

Steps to Reproduce

1. Switch to Macro - Sequence mode - Peptide type
2. Copy to clipboard big enough testx, e.g. the following one: ACDEFGHIKLMNPQRSTVWYACDEFGHIKLMNPQRSTVWYACDEFGHIKLMNPQRSTVWYACDEFGHIKLMNPQRSTVWYACDEFGHIKLMNPQRSTVWYACDEFGHIKLMNPQRSTVWYACDEFGHIKLMNPQRSTVWYACDEFGHIKLMNPQRSTVWYACDEFGHIKLMNPQRSTVWYACDEFGHIKLMNPQRSTVWYACDEFGHIKLMNPQRSTVWYACDEFGHIKLMNPQRSTVWYACDEFGHIKLMNPQRSTVWYACDEFGHIKLMNPQRSTVWYACDEFGHIKLMNPQRSTVWYACDEFGHIKLMNPQRSTVWYACDEFGHIKLMNPQRSTVWYACDEFGHIKLMNPQRSTVWYACDEFGHIKLMNPQRSTVWYACDEFGHIKLMNPQRSTVWYACDEFGHIKLMNPQRSTVWYACDEFGHIKLMNPQRSTVWYACDEFGHIKLMNPQRSTVWYACDEFGHIKLMNPQRSTVWYACDEFGHIKLMNPQRSTVWYACDEFGHIKLMNPQRSTVWYACDEFGHIKLMNPQRSTVWYACDEFGHIKLMNPQRSTVWYACDEFGHIKLMNPQRSTVWYACDEFGHIKLMNPQRSTVWYACDEFGHIKLMNPQRSTVWYACDEFGHIKLMNPQRSTVWYACDEFGHIKLMNPQRSTVWYACDEFGHIKLMNPQRSTVWYACDEFGHIKLMNPQRSTVWYACDEFGHIKLMNPQRSTVWYACDEFGHIKLMNPQRSTVWYACDEFGHIKLMNPQRSTVWYACDEFGHIKLMNPQRSTVWYACDEFGHIKLMNPQRSTVWY
3. Start new sequence (via context menu)
4. Paste text from clipboard on the canvas twice but fast (hold Ctrl key and press V key twice very fast).

Actual behavior
System put second sequence as phantom object that is not possible to delete even by clearing the canvas

Expected behavior
System doesn't allow to past from clipboard while previous operation is not finished
