Alternate Subtitle Skipping Issue in 'Seek to previous subtitle' Function

[Hyporeal]

Description: The 'Seek to previous subtitle' feature in SMPlayer is not functioning as intended. After the initial use within a session, it consistently skips every other subtitle when attempting to navigate backwards through the subtitle cues.

Steps to Reproduce:

1. Open a video with subtitles in SMPlayer.
2. Press the 'Seek to previous subtitle' shortcut (default: Ctrl+Left Arrow) to go back one subtitle.
3. Continue using the shortcut to navigate through previous subtitles.

Expected Behavior: The shortcut should sequentially navigate to the immediate previous subtitle each time it is used.

Actual Behavior: After the first usage, which correctly goes to the previous subtitle, subsequent uses of the function skip every other subtitle. For instance, if there are subtitles at 6:29, 6:24, 6:20, 6:03, and 5:50, the navigation will skip 6:20 after 6:24 and go directly to 6:03, and this pattern continues with subsequent uses.

Frequency: This issue occurs every time the 'Seek to previous subtitle' function is used after the first subtitle cue has been revisited in the same viewing session.
