pdfcomment 套件的 pdftooltip 在橫向模式下不起作用

Question

我嘗試\pdftooltip{}在橫向模式的文檔中使用 pdfcomment 套件。滑鼠懸停在正常模式下有效，但在橫向模式下失敗。在橫向模式下，只有第一個字元才會將滑鼠懸停在上面，而不是整個單字。我用這個 rmarkdown 腳本渲染 pdf（第一頁有一個正常的工具提示，第二頁有一個錯誤的工具提示）：

\pdftooltip{\mbox{mouseover1}}{this is a mouseover text}

有人知道這裡出了什麼問題？有沒有使 pdftooltip 在橫向模式下工作的解決方案？

編輯感謝評論，我有點明白發生了什麼事。似乎沒有\pdftooltip{}旋轉到橫向模式。我們該如何解決這個問題呢？
