There was a recent (end of August 2021) change in the way Stack Exchange handles such edits. When editing a closed question, now there is a checkbox to say whether the edit is substantial - and only significant edit pushes a question into the reopen review queue. So this mostly resolves the problem mentioned here - the editor only has to keep in mind not to check this checkbox if the edit doesn't bring the question to the form which would already be suitable for the reviewers. More details can be found in the announcement on Meta Stack Exchange: Review queue workflows - Final release.
This question was rendered obsolete by these changes.
One of the reasons why a question can be put on hold is that it does not fulfill standards of the site. The OP is expected to improve the question.
Review queue is here to help re-opening questions that deserve reopening. IIRC a question gets into review queue if someone votes to re-open. Another way how it gets there is if there is an edit to the question. As far as I know this only can happen once.
For this reason it would be better if the post gets into re-open review queue only after the edit by the OP in which he tried to address the issues which caused the question to be put on-hold.
When I retag a question or make a minor spelling or grammar correction, this improves the question. But if the question enters the review queue after such minor edit, the users will probably vote to leave closed. And if the OP later improves the question, it will not enter the review queue. Which means that while I was trying to help the OP by editing their question, I have lowered the chance of the question being re-opened.
- Is my understanding of the way questions enter the review queue correct? (Can minor edit send the question to the review queue? Can a question enter the review queue only once?)
- Should we (for the reasons described above) avoid minor edits of questions by other users after the question has been put on hold?
