TextView height doesn't work

[BenjaNapo]

Describe the bug

TextView height is not set properly based on text length, indeed it change drastically just adding a single character

To Reproduce

I created two ListView with just one char of difference in this way:

                <ListView
                    Margin="0,10,0,0"
                    HasUnevenRows="true"
                    ItemTapped="ListView_ItemTapped"
                    ItemsSource="{Binding DomandaAttuale.Risposte}"
                    SelectionMode="None"
                    VerticalOptions="Center">
                    <ListView.ItemTemplate>
                        <DataTemplate>
                            <ViewCell>
                                <Grid VerticalOptions="CenterAndExpand">
                                    <Grid.ColumnDefinitions>
                                        <ColumnDefinition Width="1*" />
                                        <ColumnDefinition Width="9*" />
                                    </Grid.ColumnDefinitions>
                                    <ia:Checkbox
                                        FillColor="{DynamicResource PrimaryColor}"
                                        IsChecked="{Binding Selezionata}"
                                        IsCheckedChanged="Checkbox_IsCheckedChanged"
                                        OutlineColor="{DynamicResource PrimaryColor}"
                                        Shape="Circle" />
                                    <math:TextView
                                        Grid.Column="1"
                                        FontSize="35"
                                        LaTeX="L'insieme dei nu"
                                        TextAlignment="Left"
                                        VerticalOptions="Center" />
                                </Grid>
                            </ViewCell>
                        </DataTemplate>
                    </ListView.ItemTemplate>
                </ListView>

Expected behavior

This is the result with the text "L'insieme dei nu":

And this is the result with the text "L'insieme dei num":

My instinct tells me that this is related to #136.

[BenjaNapo]

I saw that issue too but I didn't know if they were related, but if you say so I'll follow that issue👌🏻 Hope it will work for mine too when fixed :P

I've downloaded the latest Nightly Package but it still the same:

Any idea? I don't think it's my """fault""" because it shows well writing "L'insieme dei nu"

[Happypig375]

I cannot confirm this bug because I have not seen it happen yet and it is not debuggable. Try uploading a zipped file of a solution that exhibits this problem.

[Happypig375]

This is probably fixed with #136 and #137. Can you confirm?

[MartinZikmund]

Will check!

[BenjaNapo]

Height issue resolved! Nice work 😁
