Bug description

My small laptop sports a screen resolution of 1366x768.
In file explorer, when i use the drop-down menu attached to the three-dots icon on each file, the size of the window is too small to show the menu in its entirety unless i scroll down pre-emptively (i can't scroll after having opened that menu because any click outside the menu closes it afterwards).
The name of numerous options also copiously overflow the size of the menu.

This screenshot was taken in fullscreen without the windows bar below and without the browser bar above. As you can imagine, the issue is even worse without the browser window in fullscreen.

Steps to reproduce

1. Use a screen with a resolution of at most 1366x768 pixels
2. Use grid-view in the file-explorer
3. Click on the drop-down menu for any file

Expected behavior

The drop-down menu in its entirety should be visible without scrolling.
The options in the menu shouldn't have their name overflow the menu borders.
