Features that use "scanSelectedText" break some handlebars

[Kuuuube]

Description When using either the Scan selected text keybind or the Lookup in Yomitan context menu item, the following handlebars do not capture any text before the scanned text:

{sentence}
{sentence-furigana}
{cloze-prefix}

Yomitan version 0283b29

I suppose this is because _disallowExpandSelection is set to true in TextSourceRange? Hence the extractSentence in TextSourceGenerator is not functioning properly?

I think the fix involves changing this line https://github.com/themoeway/yomitan/blob/76ca08bd59f0e8bfa1bb20ac813f48e7ab241265/ext/js/dom/text-source-generator.js#L66

to not just blindly copy source (which has _disallowExpandSelection === true), but to find a way to set this value to false after copying

Might be relevant: I am also getting incorrect highlights when using the cloze-prefix/cloze-body/cloze-suffix for highlighting in sentences for Anki cards. For example, when adding 快く:

Currently switched to simply having the sentence only with no highlighting
