First blockqoted line in lists is rendered incorrectly

I’m sure this bug must’ve been reported, but I couldn’t find it by searching the forum.

In ordered or unordered lists, the first line of block quotes is over-indented by one tab if the block quotes are preceded by 2 or 3 spaces. The indentation is the same if the block quoted lines are preceded by 1 or 4 spaces, but the result is visually unappealing.

Steps to reproduce

Create a file with the following Markdown (note the 3 spaces before the > characters):

1. First list item
   > Quoted line 1
   > Quoted line 2
2. Second list item

* Unordered list item
   > Quoted line 1
   > Quoted line 2
* Another unordered list item

Expected result

This is the rendering from Discourse:

Actual result

This is the rendering in Obsidian 1.8.10. The first line is over-indented, even though both start with the same number of spaces:

Additional information

If the block quoted lines are prefixed by two space characters, only the unordered list renders the first block quoted line incorrectly:

1. First list item
  > Quoted line 1
  > Quoted line 2
2. Second list item

* Unordered list item
  > Quoted line 1
  > Quoted line 2
* Another unordered list item

Prefixing with only 1 space results in the block quote being out-dented vs. its list item:

Prefixing with 4 spaces results in an extra vertical tab:

I haven’t seen this example before, but it looks good in Reading view (right):
