Chat text breaks when mixing RTL and LTR in same line (e.g., Russian/English + Persian)

[Pakrohk]

Bug Description

When writing a chat message that mixes an LTR language (like Russian or English) with an RTL word (like Persian or Arabic) in the same line, the text rendering breaks. After typing the RTL word, the rest of the sentence jumps to the wrong side and the entire sequence becomes reversed or misordered.
This is a bidirectional (BiDi) text issue.

Example in Russian + Persian:
"Я люблю سلام как дела"
→ After "سلام", the rest ("как дела") appears on the wrong side.

Steps to Reproduce

1. Open any chat in Extera.
2. Type an LTR sentence (e.g., in Russian or English).
3. Insert an RTL word (e.g., Persian "سلام" or Arabic "كتاب") in the middle.
4. Continue typing LTR after that word.
5. Observe the broken reordering.

Expected Behavior

The sentence should display naturally with proper BiDi support: RTL text flows right-to-left, LTR text flows left-to-right, without breaking the word order (just like in Telegram, WhatsApp, or any properly implemented chat).

App Version

26.2.9

Additional Platform Information

Device: Android

Additional Context

This is likely caused by missing Unicode control characters (LRM/RLM) or incorrect textDirection / layoutDirection settings on the message input or message bubble views.
I can provide a screen recording if needed.

Hey there, I updated you today – but honestly, 185 MB is way too heavy for a mobile chat app, it should be around 50‑60 MB. Since it's built with Flutter, you really should export separate builds for each processor architecture.
And the same issue is still there (the one I mentioned before): when I write an RTL line (like Persian) and put an English word or phrase (LTR) in the middle, the whole line switches to LTR alignment and the text gets completely messed up – the beginning goes to the end and vice versa. Please fix this.

The text I typed in Telegram is in the correct RTL layout.
