User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:147.0) Gecko/20100101 Firefox/147.0

Steps to reproduce:

System: Linux Ubuntu 24.04.3 LTS

1. I hold the mouse over the tab and then the preview is displayed on the left-hand side for the tabs on the far right.

2. This problem also occurs in other places. For example, if I enter a search term in my search engine of choice and want to copy a section of the displayed results by selecting it, etc., the context menu is sometimes displayed in the upper left corner, but it is then impossible to make a selection.

Actual results:

1. The tab preview is not displayed under the corresponding tab.

2. No options such as copy etc. are available in the context menu.
