PyCharm + IdeaVim : how to disable auto-unfolding on caret touch?

Question

When editing folded Python code with IdeaVim, if the caret/cursor touches a folded zone represented by ... (or region_name if using a #region tag), the folded section immediately unfolds. I'd like to disable this behavior so that no fold ever unfolds unless specifically told to do so with a specific command.

Notes:

• I use PyCharm Community 2018.3.7, with IdeaVim 0.57, on Windows 10.
• This problem doesn't occur when I'm not in IdeaVim mode (so it's not PyCharm's "fault").
• This problem doesn't occur in Neovim 0.4.3, I guess it doesn't in other *Vims
• This doesn't affect all folded zones. Chiefly #region/#endregion folds and long comments, but not folded functions.
• This behavior seems a little random. Sometimes the zone will only unfold if I go right or left when the caret is on the ... zone, sometimes it unfolds even if I'm just "passing through" with up or down.

EDIT (based on @Feedforward's comment below):

This bug was signaled here on jetBrain's bug tracker: https://youtrack.jetbrains.com/issue/VIM-629

It was dismissed because the problem was "non-reproducible". I'll see if there's a way to arrange that, but apparently there's no hope of solving this problem anytime soon.

Unfortunately, there is no way to disable it because it's more like a bug in IdeaVim. You can file an issue on the bug tracker: https://youtrack.jetbrains.com/issues/VIM
