Cell toolbar automatic show hide inconsistent

I’m not sure whether the cause of the following is a bug or a setting.

Given a document with two text files, two jsee files and two tsv files (tab separated):

Switch from

doc1.txt    →  table1.tsv      ✓ Cell toolbar shown
table1.tsv  →  doc1.txt        ✓ Cell toolbar hidden
doc1.txt    →  jsee1.jsee      ✓ Cell toolbar hidden
jsee1.jsee  →  table1.tsv      ✗ Cell toolbar hidden ???
table1.tsv  →  table2.tsv      ✓ Cell toolbar shown
table2.tsv  →  jsee1.jsee      ✗ Cell toolbar shown  ???

I.e. switching between tab separated and jsee files leaves the cell toolbar’s visibility at its previous state.
