CTRL+D and CTRL+U doesn't work if cursor at the top ... | VSCodeVim/Vim

Nobody has claimed this yet.

As title says. But if I navigate down with SHIFT+} and use CTRL+D or CTRL+U it starts to work, if I go back at the top of the document it doesn't work again. This happens only if imports are folded.

Here are the logs:

Trying to use CTRL+U or CTRL+D, does nothing:

Use SHIFT+}:

Use CTRL+U after using SHIFT+}:

It can be reproduced in .ts file and especially large one with a lot of imports (I have 54). And it happens only if these imports are folded. If I unfold imports it works as expected.

Reproduce the issue in a large .ts file with many imports folded, checking CTRL+D and CTRL+U at the top before and after moving with SHIFT+}. Use the logs to compare key handling and selection changes; done means both commands work at the top of the document while imports remain folded.
