Partial Match issue in Find Function

You may have objected to the previous report because it was too long and AI-assisted, but I used AI only to speed up the wording and to build the technical phrasing in a more detailed and accurate way. The observations and tests are mine.

In short: the Find function behaves inconsistently in JSON/text content. A valid partial query returns 0 matches, while the full text on the same line returns 1 match. This points to a search bug rather than user error.

Example:
summits_____are hidd returns 0
summits_____are hidden returns 1

Also, this issue occurs often when the target text is outside the lines currently visible on screen. It becomes more noticeable when the scrollbar goes to the very beginning or the very end of the file. I supported this with videos. This suggests that the problem is not limited to the visible area only; rather, the search seems to stop or fail after a certain point in the internal text buffer.

update:

This looks like incomplete initialization or desynchronization of the search subsystem. Navigate through the file via Home/End temporarily restores correct matching, which suggests that viewport/navigation events force a reinitialization of the internal search context. After restart, the faulty state returns.

possible issues:

search-buffer desynchronization
