[BUG] Markdown Text Splitter - Overlap does not work

[fmancardi]

Describe the bug

I've created a document store and create 4 file loaders using always the same md file

jack_russell_guide_5pages.md

I've used 4 different configuration of splitter type, and chunk size and overlap.
Following images shows the outcome of tests

---

Here seems to exist an issue (Markdown Text Splitter)

Testing using Recursive Character Text Splitter, shows the overlap - chunk size: 1000, overlap 400

To Reproduce

1. Create a document store
2. Create a document loader of text type
3. Upload this md file jack_russell_guide_5pages.md
4. Select chunk size: 1000, chunk overlap: 200
5. Process
6. Wait till document store status will be sync
7. Access the view chunks option for the document loader just created.

No overlap seems to exists between chunks

Expected behavior

Overlaps are present, like happens when using Recursive Character Text Splitter
