Markdown problems in Agentflows V2 after flowise@3.1.1 release + no support for tables

[bogdanpop95]

Describe the bug

The upgrade from flowise@3.1.0 to flowise@3.1.1, specifically this PR #6021 from the #5527 issue caused my prompt content to be change as follows:

• **Identity lookups** (`search.ismatch`): TO **Identity lookups** `search.ismatch`):
• `searchMode`=`"any"` TO `searchMode"any"`
• `and`/`or` TO `andor`
• it automatically added line breaks between paragraphs without an initial line break

line1
line2
TO
line 1
empty
line 2

To Reproduce

Also, seems there is no support for Markdown Tables (part of the extended syntax):

Take this raw input:

### Sortable Fields (use in `orderby`)

| Field | Type | Description |
|-------|------|-------------|
| Rating | Edm.Double | Rating score. Order: `Rating desc` |

Paste in the </> Source part and then press Save.
Resulted content:

### Sortable Fields (use in `orderby`)

Paste it in the Edit part and then press Save.
Resulted content:

### Sortable Fields (use in `orderby`)

| Field | Type | Description |

|-------|------|-------------|

| Rating | Edm.Double | Rating score. Order: `Rating desc` |

Expected behavior

A rendered table in the Edit and the original markdown in the </>Source:

Hey! I reproduced this locally on v3.1.2 and can confirm both issues.

Using the Source editor, I pasted this:

### Sortable Fields (use in `orderby`)

| Field | Type | Description |
|-------|------|--------------|
| Rating | Edm.Double | Rating score. Order: `Rating desc` |

After saving, the content box showed:

Sortable Fields (use in orderby)

Two things broke:

1. ### heading was stripped and converted to just bold text
2. The entire table disappeared

I'm currently looking into the RichTextEditor component to find where the markdown is being processed incorrectly. Will update with findings and a fix soon!

Root cause: @tiptap/markdown v3 does not natively
parse markdown table syntax. Table extensions are
added but markdown serialization doesn't support tables.
