New preview doesn't update when images are selected sequentially

### Before Submitting Your Bug Report - [x] I have verified that there isn't already an issue reporting the same bug to prevent duplication. - [x] I have seen the [FAQ](https://github.com/p0deje/Maccy?tab=readme-ov-file#faq). ### Maccy Version (see 'About' window) Built from master@4cd1f97 ### macOS Version 15.7.2 ### Maccy Settings ```Shell { "KeyboardShortcuts_delete" = "{\\"carbonModifiers\\":2048,\\"carbonKeyCode\\":51}"; "KeyboardShortcuts_pin" = "{\\"carbonKeyCode\\":35,\\"carbonModifiers\\":2048}"; "KeyboardShortcuts_popup" = "{\\"carbonModifiers\\":768,\\"carbonKeyCode\\":8}"; "KeyboardShortcuts_togglePreview" = "{\\"carbonModifiers\\":4096,\\"carbonKeyCode\\":49}"; "LaunchAtLogin__hasMigrated" = 1; "NSStatusItem Preferred Position Item-0" = 194; "NSStatusItem Visible Item-0" = 1; "NSStatusItem Visible Item-1" = 0; "NSWindow Frame SUUpdateAlert" = "970 762 620 398 0 0 2560 1415 "; "NSWindow Frame com.sindresorhus.Settings.FrameAutosaveName" = "1025 889 482 314 0 0 2560 1415 "; SUAutomaticallyUpdate = 0; SUEnableAutomaticChecks = 0; SUHasLaunchedBefore = 1; SULastCheckTime = "2026-02-08 22:19:38 +0000"; SUSendProfileInfo = 0; avoidTakingFocus = 1; clearOnQuit = 0; displayLinkDetected = 0; enabledPasteboardTypes = ( "public.tiff", "public.png", "public.rtf", "public.utf8-plain-text", "public.html", "public.file-url" ); highlightMatch = bold; historySize = 200; ignoreAllAppsExceptListed = 0; ignoreEvents = 0; ignoreOnlyNextEvent = 0; ignoredApps = ( ); ignoredPasteboardTypes = ( "net.antelle.keeweb", "de.petermaurer.TransientPasteboardType", "com.agilebits.onepassword", "Pasteboard generator type", "com.typeit4me.clipping" ); imageMaxHeight = 40; maxMenuItemLength = 50; maxMenuItems = 0; menuIcon = maccy; migrations = { "2024-07-01-version-2" = 1; }; pasteByDefault = 0; pinTo = top; popupPosition = window; popupScreen = 0; previewDelay = 200; previewWidth = 534; privacyMode = 1; privacySensitiveMode = 0; removeFormattingByDefault = 0; searchMode = exact; showFooter = 1; showInStatusBar = 1; showRecentCopyInMenuBar = 0; showSearch = 1; showTitle = 1; suppressClearAlert = 0; windowPosition = "[0.544921875,0.8706713780918728]"; windowSize = "[316,714]"; } ``` ### Description I know this feature isn't released yet, but, as I was developing #1149, I accidentally ran into this issue. It looks like the preview won't update when selecting an image, if the previous item is also an image. ### Steps to Reproduce 1. Have Maccy with changes introduced at #1296 2. Add multiple screenshots in your history 3. Scroll or hover with mouse without changing to non-image item on your history
