This bug works on Windows/SystemDefault, too.

It seems to be a problem with the length.
Text truncation is also an issue that needs to be solved, but it's not as serious a bug as a misaligned layout.

We need to check of Photon behavior later.
They are similar in size, so maybe there is a solution.

This panel on Lepton should set wide width because toolItem is too fit to add icon. So, It needs to modify width of the panel.

  #appMenu-popup panelview {
    width: 30em !important; /* can modify panel width, original: 22.5em */
  }

It looks a bit wide in English.

This does not mean that there is no other way.
We can also set it up differently by language.

/* Sample Code */
:root[lang="de-DE"] #appMenu-popup panelview {
  width: 30em !important; /* can modify panel width, original: 22.5em */
}

The german language string set by Firefox is de only (checked for both Linux and Windows).
Also 23em is sufficient (at least for Linux, not tested with Windows).
This will not only be a cure for german, I suspect a few other languages with longer words are affected by this.

/* Sample Code */
:root[lang="de"] #appMenu-popup panelview {
  width: 23em !important; /* can modify panel width, original: 22.5em */
}

Proton have translation cut off problem in another language too. So, I suggest width: 25em because I think it's reasonable in many language including English.

/* Panel View */
:root #appMenu-popup panelview {
  width: 25em !important; /* can modify panel width, original: 22.5em */
}

Can I make pull request of this?

@SimYunSup LGTM
If you open the PR, I'll merge it.

Once we adjusted the default panel size.
