How to reproduce:
1. Open the attached “IN-151480” project
2. In the Project window, open Bug.uxml
3. Double left-click the Bengali text
4. Delete the the first C in “75 °C”
5. Observe the displayed text
Actual result: The Bengali text renders incorrectly with dotted circles (◌). Deleting the "C" fixes the rendering
Expected result: The Bengali text renders correctly whether or not Latin characters are present
Reproducible with: 6000.0.0f1, 6000.0.82f1, 6000.3.23f1, 6000.5.10f1, 6000.6.0b10, 6000.7.0a5
Reproducible on: macOS 26.5 (M1), Windows 11 (By reporter)
Not reproducible on: No other environments tested
Note: In the 6000.0.X stream, the bug behaves differently. If the text is still highlighted when viewing the bug, the dotted circles remain visible, unlike in other streams, where the issue disappears instantly after the English character is deleted
