In code blocks, fast insertion of spaces for indentation inserts a dot

[laikoni]

I stumbled over a weird behavior with indentations in code blocks.

Steps to reproduce

Consider a code block like the following where some lines are indented:

```
   ab
cd
   ef
```

I place the cursor in front of cd and press the space bar three times in short succession.

Expected result

cd is now aligned with the other lines:

```
   ab
   cd
   ef
```

Actual result

When hitting the space bar fast enough, instead a . and a space are inserted and the first character is removed:

```
   ab
. d
   ef
```

Further observations

• This does not happen when I am typing outside of a code block
• There needs to be an indented line before and after the affected line
• The surrounding lines need to be indented with at least 3 spaces or one or more tabs
• reproducible in the sandbox vault

Environment

• Operating system: macOS Ventura 13.0.1

I can’t reproduce. Maybe you have a text expander that is doing this.

I found the culprit: There is a setting on macOS to insert a dot on double-space, something that apparently was adapted from iOS a while ago.

Turning this setting off removes the issue for me.

However, it is worth noting that with the setting turned on, the behavior of the obsidian editor is still buggy, given that a double-space is usually ignored except under very specific conditions as described above, and also the removal of the next character should not occur.
