bug(mac): When using Farsiman keyboard, the cursor stays on the far right of the text at times even though it's for RTL language

[MakaraSok]

Describe the bug

macOS Catalina/BigSur - Notes - the cursor is shown on the left at first, but upon pressing the spacebar it jumps to the far right.

macOS BigSur - LibreOffice - the cursor is always shown on the far right while the texts output on the far left.

The above behavior doesn't show when testing with TextEdit on macOS BigSur. The cursor always stays on the far left as expected.

Expected behavior

The cursor should always be shown on the far left as Farsiman keyboard is RTL.

Note that the keyboard has correctly been marked as RTL in the .kmn.
