[Bug][Mobile]: A table right after a line of text renders as a run-on paragraph #20115

Steps to reproduce

1. Have an agent reply with a table placed directly under a line of text, with no blank line between them:

   Companies we already have on file
   | Company | Fit | Contact |
   |---|---|---|
   | Acme | A | email |
   | Globex | B | form |

2. Open the thread in the mobile app.

Expected behavior

The table renders as a table, as it does on web and desktop. GFM lets a table interrupt a paragraph (the line before the delimiter row is the header row), and agents often write tables this way.

Actual behavior

On mobile the whole block renders as one paragraph. The soft line breaks become spaces, so rows run together as | Acme | A | email | | Globex | B | form |.

Cause: mobile parses Markdown with md4c (vendored in react-native-enriched-markdown). md4c only accepts a table delimiter row when the current paragraph has exactly one line (cpp/md4c/md4c.c, ctx->current_block->n_lines == 1 && md_is_table_underline(...)). With a lead-in line, the paragraph already has two lines when the delimiter row arrives, so md4c never starts a table. Web uses remark-gfm, which handles this case.

Adding a blank line between the text and the table makes mobile render it correctly.

Impact

Agent replies that contain tables are hard to read on mobile. The model decides whether to add the blank line, so this happens regularly with no way for the user to fix it.

Workaround

Ask the agent to put a blank line before tables.
