Bug in Thunderbird plugin

The Languagetool Thunderbird plugin does copy some text from the popup window in the email. It happens if I send the email before closing the LanguageTool Add-on Windows.

Thunderbird 128.3.0esr(64-bit)
Language Tool Addon Version
8.11.2


I attached a screenshot for information.

Thanks for the report, I’ve created an internal ticket for our developers.
