When sidebar is narrow, the buttons on hover are clipped away

[krassowski]

Description

When git sidebar is resized, if there is a file with longer file name the button get cut off.

The problem with current behaviour is that some buttons are not visible and user may mis-click when moving from one item to another because the buttons jump position.

Reproduce

On the animation below

• See no problem when sidebar is wide
• Wait until the sidebar is resized
• See there is a problem when sidebar is narrower

Expected behavior

It would be easier for users to select desired action if the buttons were kept visible but instead the file name was trimmed with an ellipsis ... - which is already happening but somewhat not to the necessary degree.

Context

• Extension version: 0.50.0rc0
